Question

A leaf falls from a tree. As you are watching the leaf fall, how can you tell that it has reached its terminal velocity?
A. The leaf is accelerating.
B. The leaf hits the ground.
C. The leaf is experiencing a force.
D. The leaf is falling with a constant velocity.

Answer 1

You can tell that it has reached its terminal velocity when D) the leaf is falling with a constant velocity as you are watching the leaf fall. The terminal velocity is a point of condition when an object's speed equalize the force of gravity. The terminal velocity condition could occur if there is no acceleration to the object's speed.
