Its the air resistance that causes the free falling body to reach its terminal velocity
As objects fall, they are accelerated by the force of gravity, which causes them to continually fall faster, until they either reach the ground, or until they reach what is known as terminal velocity, which is the speed at which air resistance is equal to the force of gravity, so that the falling object does not accelerate any more.
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.
ahhh physics.......i love it.... but it is terminal velocity :)
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 their shape and mass so it is different for different objects. Also some objects take a long time to reach their terminal velocity so they have to be dropped from very high up in order to have time to reach terminal velocity before hitting the ground.
No. It may crash before it does so. Or air resistance may simply be negligible, as in objects in outer space.
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.
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.
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.
Yes. - And please don't combine "does" and "is" in the same question that way.
