In This Lesson:
Energy and Everyday Devices
- In this activity, you will use what you know about types of energy to describe the consumed energy and the produced energy in different devices.
- The following table shows the function, the energy consumed and the energy
produced in some devices:


Energy chain while riding a bike

Energy chain when a light bulb is switched on

Energy can be changed from one form into another, where the new energy cannot be created from nothing, and the old energy does not disappear but it changes from one form of energy into another, this is called " law of conservation of energy"

The law of conservation of energy
Energy can neither be created nor destroyed, but only converted from one form of energy into another.

بالتوفيق
