Worked Solution

Step 1: Gravity is a constant pulling force near the Earth. Step [2-9]: It pulls all objects with mass toward the Earth's centre. Step [2-9]: Air resistance is also present but acts upward, opposing the fall.

Correct answer: Gravitational force pulls the ball toward the centre of the Earth.
