A ball is projected vertically upwards and then falls back to its original position.
Once projected, the ball experiences only a single force, downwards, due to a constant gravitational field strength of 10 N/kg.
Here are three statements about the ball:
- When the ball is moving upwards it loses kinetic energy and gains potential energy.
- The magnitude of the ball’s acceleration increases as it falls.
- No vertical forces act on the ball when it is at its maximum height
Which of the statement(s) is/are correct?
A. 2 and 3 only
B. none of them
C. 1 and 2 only
D. 3 only
E. 1 only
