Energy TRANSFER is the passing of energy from one object to another object.
Energy TRANSFORMATION is the changing of energy from one form of energy to another form of energy.

3. Mass Vs Weight Is weight and mass the same???
No, mass is referred to as the amount of matter in an object.
But Weight is the gravitational force an object experiences due to its mass.

4. Power Power is the rate at which energy is transferred or transformed.
So if I am carrying a suitcase while going upstairs which has more power…if I walk slowly or run up the stairs?
Power = Energy Transferred
Time

5. Friction

6. The Law of Conservation of Energy
Energy is never created or destroyed!
The total amount of energy will always remain the same!
