Advanced Science Primary 6 Energy

A ball is dropped from a height. As it falls, what happens to its Gravitational Potential Energy (GPE) and Kinetic Energy (KE)?

A Both GPE and KE increase
B GPE decreases, KE increases
C Both GPE and KE decrease
D GPE increases, KE decreases
Show Worked Solution

Worked Solution

Step 1: Height decreases as the ball falls, so GPE decreases. Step 2: Speed increases as the ball falls, so KE increases. Step 3: Energy is being converted from GPE to KE.

Correct answer: GPE decreases, KE increases
