Does velocity of falling body changes as it falls?

Question

Does velocity of falling body changes as it falls?

Answer 1

yes. specifically, it accelerates.

Answer 2

Yes and no.  If a skydiver jumps out of an aeroplane, for an initial period of time he or she will accelerate, due to the downward force of gravity.  However, as his or her velocity increases the upward friction force due to air resistance will increase, until at a certain velocity this will balance the gravitational force and the skydiver will stop accelerating and fall at a constant velocity (known as the "terminal velocity") from that time onwards.

Answer 3

At the earth's surface it increases at 16ft per second squared.

  Without the atmosphere all objects will do the same no matter their weight or size.

  In the atmosphere it will change  for ever thing depending on their weight and size.

Answer 4

yes velocity of free falling body keep on changing .

*  Since, earth exert gravitational force on all body,in practical

air resistance resist gravitional force which resist the acceleration.

*  For the sake of calculation wee use acceleration due to gravity ad 9.8 m/s^2.

*  When we apply Newton's laws of amotion we find v=a*t

:. body keep on accelerating,thus increase its velocity when moving back to earth and decrease when move above earth.

Answer 5

yes. it increases.

v=a*d

This holds in vacuum, or for low falls.

It does not take into account wind resistance.

Wind resistance increases with velocity.

There is a point where wind resistance is as great as acceration called terminal velocity. This depends on the shape and mass of the falling object.

An object's velocity will not change from terminal velocity (expect when it hits the ground or something).

Answer 6

Yes it does ~~
