Standard Science Primary 6 Energy

Study the energy conversion of a toy car released from the top of a ramp: Potential Energy → Kinetic Energy → Sound + Heat. At which point does the car have the MOST kinetic energy?

A Halfway down the ramp
B At the bottom of the ramp
C At the top of the ramp
D When it comes to a stop

Worked Solution

Step 1: As the car moves down, potential energy is converted into kinetic energy. Step [2-9]: Kinetic energy increases as speed increases. Step [2-9]: Speed is highest at the bottom of the ramp before friction slows it down on the flat ground.

Correct answer: At the bottom of the ramp
