Why is terminal velocity in water less than the terminal velocity in air?
The incompressibility, inertia and relatively higher viscosity of water make it difficult to displace, so its reactive forces on the falling object are greater; hence the terminal velocity is reduced.
More resistance, caused by a greater density.
because there is more air resistance
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
There is no such thing as "maximum terminal velocity", neither on Jupiter nor hear on Earth. The "terminal velocity" depends on the specific object - and on the atmospheric conditions. For example, a very heavy object will typically have a larger terminal velocity than one that is very light; and near Earth's surface, the terminal velocity (for a given object) will be smaller than in the upper atmosphere, where there is less air resistance.
How would the terminal velocity of an object falling towards earth differ than the terminal velocity of the same object falling through water?
because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity
Terminal velocity is the velocity at which the force of gravity is balanced by the force of air resistance. The (falling) object does not go any faster than terminal velocity.
Yes, until he reaches terminal velocity.
High Velocity is short for "high terminal velocity" which is another way of saying that the blood spatter is small and is so small, in fact, it is the smallest of other velocities: • Low terminal velocity • Medium terminal velocity The high velocity pattern is usually less than one millimeter in diameter and is known to fall up to around 100 feet per second.
Usually not. Most objects have a terminal velocity that is considerably less than the speed of sound.
Honey is a more viscous fluid than water.
Assuming this is a free fall on the earth, the highest velocity an object in free fall can reach is 9.8 meters per second or 32 feet per second. answer 2. above is described the acceleration due to gravity on Earth. The Q asks for the Highest velocity. This is known as the Terminal Velocity. This depends upon buoyancy, air-resistance and so on. The terminal velocity of a Parachutist is much less than that of… Read More
If the object falling is falling at a constant velocity, i.e. terminal velocity, then the upward force of air resistance will be equal to the downward pull of gravity. If not, then the force of air resistance will be less than the pull of gravity, and the object will be accelerating with a force equal to the difference, until terminal velocity is reached
The terminal velocity of a falling object depends upon its aerodynamics (which is to say, its shape) rather than its size and mass.
Terminal velocity for a feather will be considerably lower than the terminal velocity of a bullet. The size and shape of the object will play an important role. While objects dropped from a given height in a vacuum will fall to earth at the same velocity, the resistance caused by atmosphere will be different for different objects.
When terminal velocity has been reached.
The golf ball has less air resistance then the tennis ball, and so accelerates slightly quicker (it will also have a greater terminal velocity).
Terminal velocity There is more than one explanation for terminal velocity, I think you are asking about a person or skydiver as opposed to a bullet. Terminal velocity is the velocity reached when the drag force equals the weight of the body minus the buoyant force, which halts acceleration and causes speed to remain constant. the terminal velocity of a skydiver in a normal freefall position with a closed parachute is about 120 mph or… Read More
Why is it that a cat that falls from the top of a 50-story building will hit a safety net below no faster than if it fell from the twentieth story?
At a certain height, any object will reach terminal velocity. Terminal velocity is the term for the maximum velocity that an object will reach in a specific gravity well. In this case, the cat will reach terminal velocity from 20 stories, so the additional height does not matter.
Terminal velocity is when air drag stops you from going any faster when falling. A heavier person will fall with greater force than the light sky diver falls at. So the heavier skydiver will require more force from air in order to keep him/her at terminal velocity
An object falling through the air will have a terminal velocity of approximately 120-140mph. The less "wind resistance" it has the faster it goes. Although the penny has less wind resistance than say, an elephant, it still is not an ideal shape for moving through the air. Being flat, it can flutter, spin, 'float', etc, and that will slow it down.
i think it's 2
Ants have a couple of things going for them, but mainly physics of airflow. In essence the terminal velocity of an ant in air is much slower than that of a human. Terminal velocity is the speed and which air resistance forces counter balance gravity and you do not accelerate (go any faster) anymore while falling. The terminal velocity of an ant is about 4 mph whereas a human is well over 100 mph. So… Read More
Deceleration (or negative acceleration).
Why is it that a cat falls from a 50 storie building will hit a safety net below no faster than it fell from a 20th story?
It reaches terminal velocity. The speed is limited by the air resistance of the object. In most cases, terminal velocity is reached in a few seconds.
Assuming the only difference is mass and that two objects have the same shape and size, it will take longer for the heavier object to reach terminal velocity than the lighter object. The terminal velocity of the heavier object is greater than that of the lighter object. Since the two objects accelerate at nearly the same rate at slower velocities, the time to reach terminal velocity will increase as weight or mass of the object… Read More
If a parachutist jumps from an aircraft and fall through the air what is terminal velocity before and after the parachute opens?
During free fall, the parachutist reaches a terminal velocity (a constant velocity) of somewhere between 120 and 180 miles per hour. (If you go feet first, you go faster than if you lie on your back or front). When the parachute opens (hopefully), the terminal speed is reduced to around 12 miles/hour.
The greatest velocity any object can have on earth is it's terminal velocity. That means when the force of gravity is eventually overcome by the force of air resistance of the falling object. An example of this would be that a falling feather reaches its terminal velocity much quicker (and therefore falls much slower) than something that is more dense and aerodynamic, such as a bowling ball or a baby.
viscosity of mercury is lesser than of water,because shear stress developed in water is more than mercury, this is taken from the relation viscosity is directly proportional to the shear stress and inversely proportional to velocity gradient.from fluid mechanics.
Because the moon is much less massive than the Earth, and therefore has lower surface gravity (about 1/6 of Earth's).
Factors that affect terminal velocity · Mass An increased mass will increase the terminal velocity and make the falling object reach the ground quicker. · Surface Area If the surface area of an object is increased then its terminal velocity will decrease. This is because it will have larger air resistance acting upwards on the object; therefore the object will travel at a slower rate. · Shape Shape does affect the terminal velocity of a… Read More
A free-falling object achieves its terminal velocity when the downward force of gravity (Fg) equals the upward force of drag (Fd). This causes the net force on the object to be zero, resulting in an acceleration of zero, which means the object then falls at a constant speed. So, objects with little drag, like cannonballs have a much higher terminal velocity (about 220 miles per hour) than objects with lots of drag like skydivers falling… Read More
The velocity of light in a liquid sample is always less than the light in air The velocity of light in a liquid sample is always less than the light in air
Under most circumstances, a falling object is slowed by any fluid through which the object falls. In normal, real world circumstances, this is the air or water. There are attributes of the fluid that will also affect the rate of fall. The amount the object is slowed depends on how fast it is going, its shape and weight, and the viscosity and density of the fluid. The faster the object is going, the greater the… Read More
If you mean in atmosphere, the answer is "yes". It's called "terminal velocity." What the velocity is depends upon the shape of the object, because of the resistance of the atmosphere. Mind you, not the weight, since all objects are accelerated at the same rate in gravity. But if you're a great wide object, your terminal velocity (the fastest you can go) will be lower than if you're a ball bearing. In the absence of… Read More
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
if the velocity is positive to start with it changes direction when the velocity is less than zero; that is, when it is negative.
32 feet per second per second is the standard acceleration. As the object accelerates (usually downwards due to gravity), the drag force acting on the object increases. At a particular speed, the drag force produced will be equal to the downward force, mostly the weight (mg), of the object. Eventually, it plummets at a constant speed called terminal velocity (also called settling velocity). Terminal velocity varies directly with the ratio of drag to weight. More… Read More
Based on two classes' worth of research on terminal velocity I'd say it's good for keeping some falling objects from reaching a speed that will, literally, be "terminal" (fatal) to whomever it hits. I was researching the myth behind whether or not a penny dropped off a tall building will kill some unlucky pedestrian below. All of my sources say it's impossible for said penny to do more than sting the person (barring them being… Read More
When a body attains terminal velocity its drag force and gravitational force on body cancels each other then why does the body still comes down instead of floating?
When the gravitational and drag forces on the object are equal, there is no net force acting on the object. This means that the body will not accelerate; it will not change it's velocity. In order for the body to slow down to "floating speed", the drag force would have to be greater than the gravitational force. Drag force is dependent on velocity though, so the greater the velocity the greater the drag. Since the… Read More
The bottom surface of a car will not be of smooth to make it Float. By the way, even a small boat, whose said surface is smooth, even at zero velocity, due to buoyancy force exerted by the water, it floats. If one really wants to make a ca (whose density is more than the water at displaced area)with smooth boat like bottom surface, the velocity should be such that the water should would exert… Read More
A rocket ship leaves earth's atmosphere its initial velocity is less than its final velocity which is this an example of?
if acceleration is <0 and velocity =0 then you got the handbrake on
Density! Night air is colder, therefore the atoms vibrate less. A denser medium conducts waves faster than a less dense one does. Thats also why water conducts sound faster as well.
The maximum speed you can reach is also known as terminal velocity and this is the speed at which your mass is resisted by the air. Typically in a belly to earth body position, this is around 120mph. It takes around 10 seconds to reach this speed. The minimum exit height is 2500ft and would not reach this terminal velocity before they need to deploy their parachute. Most skydivers jump from a lot higher… Read More
The viscosity of air provides a drag force on a raindrop and keeps it from falling with the acceleration of gravity. When a drop is falling (assuming it does not combine with other drops in the process) it will reach a terminal velocity which depends on its diameter. The larger the diameter the larger the terminal velocity. Specifically, the terminal velocity is proportional to the square root of the diameter of the drop. Big rain… Read More
When you drop some soil into water, gravity pulls all the particles downwards. Some bits float because their density is less than that of water. The more dense particles sink, but their downward motion is restricted due to friction between their surfaces and the water in contact with them. Large heavy particles like gravel fall quickest, partly because of their higher density, but mainly because they have less surface area per unit mass and thus… Read More
Because they are strapped into the seat with more than one belt. because of the terminal velocity
The Terminal velocity depends on a few properties of the object falling and the medium that the object is falling through. 1.
