Domanda 51 di 51

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: 1 When the ball is moving upwards it loses kinetic energy and gains potential energy. 2 The magnitude of the ball’s acceleration increases as it falls. 3 No vertical forces act on the ball when it is at its maximum height.

Which of the statement(s) is/are correct?
