Worked Solution

Step 1: Weight (gravitational force) is calculated as mass x gravity. Step [2-9]: Near the Earth's surface, the acceleration due to gravity is effectively constant. Step [2-9]: Since the mass of the ball does not change, the force remains constant.

Correct answer: The force remains constant.
