Standard Science Primary 6 Energy

A ball is dropped from a height. As it falls towards the ground, what happens to its potential and kinetic energy?

A Potential Energy decreases, Kinetic Energy increases
B Both decrease
C Potential Energy increases, Kinetic Energy decreases
D Both increase
Show Worked Solution

Worked Solution

Step 1: As height decreases, Gravitational Potential Energy decreases. Step 2: As the ball speeds up while falling, Kinetic Energy increases. Step 3: Energy is converted from GPE to KE.

Correct answer: Potential Energy decreases, Kinetic Energy increases
