Worked Solution

Step 1: Gravity is an attractive force exerted by Earth on all objects. Step 2: It does not require contact and acts continuously. Step 3: Whether the ball is moving up, at the peak, or falling down, gravity is pulling it toward the centre of the Earth.

Correct answer: The gravitational force acts on the ball at all times.
