Standard Science Primary 6 Energy

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

A GPE decreases, KE decreases
B GPE increases, KE decreases
C GPE decreases, KE increases
D GPE increases, KE increases

Worked Solution

Step 1: GPE depends on the height of the object. Step 2: As the ball falls, height decreases, so GPE decreases. Step 3: As it falls, it moves faster, so KE increases.

Correct answer: GPE decreases, KE increases
