The greatest velocity a falling object can reach?
Its the air resistance that causes the free falling body to reach its terminal velocity
The fastest velocity a falling object can reach is called its terminal velocity. This happens when the force of air resistance is equal to the downwards force of weight (gravity), so the object is in equilibrium, and thus reaches a constant velocity.
ahhh physics.......i love it.... but it is terminal velocity :)
Terminal velocity. It occurs when the force of gravity is equal to the force applied by air resistance in the opposite direction. With equal and opposite forces the object can not accelerate and falls at a constant speed. Every object has a different terminal velocity and depending on the surface area, can also be manipulated
When it's weight balances the air resistance
Yes. - And please don't combine "does" and "is" in the same question that way.
A falling object accelerates at a rate of 9.8 m/s2. That means that for every second that it is falling, its velocity increases by 9.8 m/s. The higher that the object is falling from, the longer it will have to speed up, thus the higher its velocity upon impact will be. (This is assuming that it does not reach terminal velocity, the velocity at which an object can no longer accelerate because it is travelling… Read More
For a falling object, when the Force due to gravity (The weight of the object) and the Wind resistance force (A Frictional force) are equal, the object is at it's terminal velocity.
When an object falls, air resistance causes it to reach a terminal velocity. After that, it does not increase the speed of falling, no matter how far it has still to fall.
The Answer Is Roughly 7 Miles Per Second
There is no drag in a vacuum to act against the acceleration.
Gravitational force and the force of friction (the friction of the object and the air).
No, mass does not have an effect on a falling object, as long as the object is falling in a vacuum. If an object is falling through air, then aerodynamics come into play. For example, a 1' solid steel sphere will reach a higher terminal velocity than a 1' polished wood sphere.
No. If its acceleration decreases, its velocity will decrease. This is due to air resistance. If a body is high enough when it starts falling, it will eventually reach constant velocity, called terminal velocity, at which point the acceleration is zero.
As a falling object speeds up, at some point the amount of air resistance is equal to the acceleration of gravity, and the object then falls at a steady velocity known as the terminal velocity, until it impacts the ground. Notice that this behavior has nothing to do with gravity in general or the Earth in particular. It's all the result of air.
Terminal velocity is the velocity where the force of gravity balances the drag of the air stream flow past the object. At terminal velocity, the object's acceleration due to gravity becomes zero, and the object begins to fall at a constant velocity. In a vacuum, however, there is no air - and thus no drag- so the object continues to accelerate.
When the downward force on it as a result of gravity is matched by the upward force on it as a result of air resistance.
Without air, the speed of a falling object keeps increasing, and never reaches a maximum. The only thing that causes it to reach a maximum and stop increasing is air resistance. The effects of air resistance depend on the size, shape, and composition of the object, and the calculation of the "terminal velocity" in advance is very complex.
If we are talking about something in the Earth's atmosphere then No, the object will reach a thermal velocity after which the velocity remains constant. If we are talking about something falling where there is no atmosphere but still an attractive gravitational mass then yes.
If you throw an object towards the ground would it acceleration be greater or less thatn an object free falling?
Both objects would eventually reach terminal velocity which means they would both fall at the same speed.- But - compared to the falling object, the downward acceleration of a thrown object is the same.
It has been proven that the speed of light (about 3 x 108 meters per second) is the maximum speed any object can reach.
That varies, depending on the object. A massive object may take a long time to reach terminal velocity; a less massive object will reach terminal velocity faster. It basically depends on the object's mass, size, and shape.
What happens when the drag force of air resistance is equal to the force of gravity on an object as it is falling?
This state is known as terminal velocity. In it's current shape, an object as described cannot travel any faster. The force of gravity is constant where as the force of air resistance increases with velocity so it takes time for an object to reach its terminal velocity.
No. It may crash before it does so. Or air resistance may simply be negligible, as in objects in outer space.
The difference between free fall and terminal velocity i that free fall is when an object is falling or descending through the air with little air resistance or drag. Terminal Velocity, on the other hand is when the resistance of air and the force of gravity balance each other out causing the object to reach a constant velocity. .
At a certain speed, the downward pull of gravity will be compensated by the upward force of air resistance - so the object will no longer accelerate.
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
the terminal velocity is the total speed that its take an object to reach the point it required from the initial velocity
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as… Read More
Using 32 ft/sec2 as the acceleration due to gravity, it would be 0.0303.. miles per sec.
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
It depends on how high it is when it start falling. If it is high enough, it will reach its terminal velocity and stop accelerating before it hits the ground. As an object is falling, it has to push through air below it. The faster it falls, the greater the air resistance (or drag) to the object. At some point, the amount of air resistance will be equal to the pull of gravity (its weight)… Read More
I think it depends on the distance it is falling from. The longer it falls the more momentum it gains. _________ The idea is called 'terminal velocity'. For a skydiver in the typical flat open position (to maximize drag) the terminal velocity is about 195 mph. Where objects can fall in vacuum, there is no termal velocity, except for the moment of impact with the body responsible for the gravitational field, at which time velocity… Read More
No. Terminal velocity is a limiting velocity, reached when a falling object's drag to wind resistance equals the force of gravity. For instance, on the Earth, a human being's terminal velocity is about 200 kilometers per hour, depending on drag which is depending on how the arms and legs are held. On the moon, however, there is no atmosphere - it is in a vacuum - so there is no wind resistance due to velocity… Read More
The acceleration of gravity is 32 feet per second, per second. This means that --eliminating any obvious aerodynamic considerations as there would be with, say, a feather -- the speed at which an object falls increases proportionately to the time it is falling. An object falling from a greater height will be falling for a longer time period and thus will reach a higher velocity and impact the ground with a greater force than one… Read More
Drag force, or the force of air friction for a falling body, increases with speed. A falling object will reach a speed at which the force of air friction will be equal to and opposite the force of gravity. At that point, the object will no longer accelerate. It's speed will remain constant, and we call that speed (and direction) its terminal velocity.
Escape velocity is the velocity that an object needs in order to reach infinite distance, wherein the force will equal to zero. Orbital velocity is the velocity of an object so it can stay in orbit.
Objects in freefall only accelerate at 9.8m/s2 if air resistance is ignored. Because friction will gradually cause a falling object to reach terminal velocity, most objects won't accelerate at exactly 9.8m/s2.
Despite how odd it may seem, an object never actually achieves its terminal velocity. The way air resistance works is that it provides a force proportional to the current velocity of the falling object. This results in the object experiencing less and less force as it slows down. The falling object will just keep getting closer and closer to its terminal velocity without ever actually achieving it. At the very least however, you can figure… Read More
When objects reach terminal velocity what are the forces involved and describe the velocity of the object?
When an object is at terminal velocity, the two forces due to gravity and drag are equal, so the object ceases accelerating. Its motion is constant and vertically downward.
I will try and help you with this one.. terminal velocity is when a object falling has reached its fastest falling speed and will stay at this speed reaching a terminal velocity is due to friction in the air although you can't see them air particles offer resistance when passed through them untill the object changes its shape..eg aerodynamics...for example a sky diver will fall at about 80\100 mph...but if they dive down there will… Read More
all objects have a terminal velocity once youu reach terminal velocity you can not fall any faster
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.
It depends what is falling and from how high. Anything falling from a great height will reach maximum velocity (when it cant fall any faster)
When objects fall gravity causes them to increase their speed. The speed would continue to increase if there was no atmosphere. But the atmosphere causes friction which prevents the object from continually increasing its speed. At some point in the fall the object reaches what is called its "terminal velocity". This is the maximum speed it reaches when the frictional force prevents it from going any faster. The terminal velocity of falling objects depends on… Read More

Escape velocity is the minimum velocity (or speed) that an object would need to reach to 'escape' the orbit of a planet.
