Forms of Energy

1. Unit 26 Types of Energy

2. Law of Conservation of Energy Energy can neither be created nor destroyed. Energy changes from one kind to another. The total energy of an object never changes.

3. Kinetic Energy Anything that has mass and movement has kinetic energy. The kinetic energy of an object in this case is given by the relation: KE = (1/2)mv2 m=mass of the object V=velocity of the object The greater the mass or velocity of a moving object, the more kinetic energy it has.

4. Kinetic Energy The greater the mass or velocity of a moving object, the more kinetic energy it has.

5. Potential Energy Potential energy is the energy stored in a system. It is the energy that can be released to become kinetic or another form. PE = mgh PE = Energy (in Joules) m = mass (in kilograms) g = gravitational acceleration of the earth (9.8 m/sec2) h = height above earth's surface (in meters)

6. Potential Energy

7. Mechanical Energy Mechanical energy is also the total amount of kinetic and potential energy in a system. Wind-up toys, grandfather clocks, and pogo sticks are examples of mechanical energy. Wind power uses mechanical energy to help create electricity. Potential energy + Kinetic energy = Mechanical energy
