Worked Solution

Step 1: Stronger gravitational pull means a greater force pulling the object down. Step [2-9]: A greater force results in the object falling faster and reaching the ground in less time. Step [2-9]: Planet Z has the shortest time (1.2s), meaning it has the strongest pull.

Correct answer: Planet Z
