What else can I help you with?
Will a man in a parachute when the air resistance is less than his weight accelerate?
Yes, until he reaches terminal velocity.
Why is the terminal velocity in water less than the terminal velocity in air?
More resistance, caused by a greater density.
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
Yes, when an object is released in a fluid and starts falling, the drag force is initially less than its weight. As the object accelerates, the drag force increases until it equals the weight of the object, at which point the object reaches terminal velocity.
When you skydive Why don't you hit maximum speed before you hit the ground?
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 - between 10,000ft and 15,000ft. This gives them a freefall time of over 45 seconds and therefore they reach terminal velocity. Once the parachute is open, the decent rate is less than 10mph, so no you do not hit the ground at maximum speed in answer to your question.
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.
What is the maximum terminal velocity on planet Jupiter?
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.
Why does an object with a large surface area reach terminal velocity before an object with a small surface area?
An object with a large surface area experiences more air resistance, which increases as the object accelerates. This causes the object to reach terminal velocity quicker compared to an object with a smaller surface area, which experiences less air resistance and takes longer to reach terminal velocity.
Which is greater - the terminal velocity of a small blood droplet or the terminal velocity of a large blood droplet?
The terminal velocity of a large blood droplet is greater than the terminal velocity of a small blood droplet. This is because larger droplets have more mass, which increases their gravitational force and air resistance, allowing them to fall faster until they reach a balanced terminal velocity.
What is the terminal velocity of falling objects in water?
Terminal velocity of falling objects in water depends on the object's shape, size, and density, as well as the water's viscosity. Generally, small objects like spheres have lower terminal velocities due to less drag, while larger or less streamlined objects will have higher terminal velocities. The terminal velocity is reached when the force of gravity on the object is balanced by the drag force acting in the opposite direction.
What does high velocity blood spatter means in a crime scene?
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.
How can you reduce your terminal velocity?
By decreasing your friction. Making the falling body more streamlined such that the "bow wave" is decreased, and the partial vacuum behind the falling body (drag) is efficiently filled, as well as reducing the interaction between the surface interface between the falling body and the air moving past it. Each of these will increase the terminal velocity. However, one eventually reaches a maximum which cannot be exceeded.
Is there a sonic boom during fall?
Usually not. Most objects have a terminal velocity that is considerably less than the speed of sound.
