Advanced Science Primary 6 Energy

A ball is rolling down a smooth ramp. At which point is the Kinetic Energy of the ball increasing?

A As it travels from the top to the bottom
B Only at the top
C At no point because the ramp is smooth
D Only at the bottom

Worked Solution

Step 1: As the ball rolls down, it loses height, so Gravitational Potential Energy (GPE) decreases. Step 2: The GPE is converted into Kinetic Energy (KE). Step 3: Because it continuously loses height and speeds up, the KE increases during the entire trip down.

Correct answer: As it travels from the top to the bottom
