[10/2] Energy Activity Book: Activity 3 - Windmill

Kinetic Energy - Some Important Key notes

Misconception: The amount of kinetic energy in a moving object depends only on the speed of the object.

• Besides the speed of the object, kinetic energy also depends on the mass of the object.

Kinetic Energy can come from the wind (moving air) or moving water. Movement of the air or water can cause an object to move. We say the energy is transfered to the object.

Observing the Windmill under the fan

The windmill rotates quickly and slow down and rotates quickly again.
It is dependent on the wind direction wind speed and the location where we place the windmill.
