Show Worked Solution

Worked Solution

Step 1: Gravitational force (weight) depends on mass and the Earth's pull. Step [2-9]: These factors do not change significantly during the ball's short flight. Step [2-9]: Therefore, the force remains constant (horizontal line).

Correct answer: A straight horizontal line
