Explain terminal velocity as the state in which drag balances the driving force and acceleration is zero.
The ball in (b) leaves the toy at point A and moves vertically upwards through the air. Point B is the position of the ball when it is at maximum height h above point A , as illustrated in Fig. 3.2.
Fig. 3.2 (not to scale)
The gravitational potential energy of the ball increases by 0.60 J as it moves from A to B .
When there is air resistance, the ball takes time T to move from A to B .
State and explain whether the time taken for the ball to move from A to its maximum height will be more than, less than or equal to time T if there is no air resistance.
