2. Energy Transformations & Conservation
Niagara Falls Mechanical energy is transformed into electrical energy!

3. Energy Transformations
A change from one form of energy to another form of energy.
Many forms of energy can be transformed into other forms.

11. Law of Conservation of Energy Songs

12. Law of Conservation of Energy
Energy cannot be created or destroyed, but it can be change from one form to another.
No energy is destroyed in the process of energy transformation.

13. Energy and friction
If you set a spinning top in motion, will the top spin forever?
What happens to the energy? Is energy destroyed? Energy is transformed to thermal energy due to friction.

14. Energy and friction
Mechanical energy is transformed into thermal energy
Friction= force one surface exerts on another when two surfaces rub together
fricción
Rub your hands together. What happens?
