Exploring Human Energy Concepts in Chapter 1

Why is it generally easier to gather evidence for kinetic energy compared to potential energy?

• Potential energy is always invisible.

• Kinetic energy is associated with motion, which is easier to observe.

• Kinetic energy can be measured with a thermometer.

• Potential energy does not exist in real life.

What is the main purpose of using wind-up toys in the demonstration?

• To explore the concepts of kinetic and potential energy.

• To learn about the history of wind-up toys.

• To see which toy moves faster.

• To understand how toys are made.

How can you prove that one of the wind-up toys has potential energy stored in it?

• By measuring its temperature

• By checking its weight

• By listening to the sound it makes

• By observing it move after being wound up
