3. Mechanical Energy The energy of motion that does the work
Combination of Kinetic AND Potential energy
Objects have mechanical energy if they can do work
More mechanical energy = More work
Example: When a spring is coiled up or a rubber band is stretched, mechanical energy is stored in it. When the spring uncoils or the rubber band snaps back, this energy is released

5. If an object has 50 joules of kinetic energy and 237 joules of potential energy, what is its mechanical energy?

6. Describe with examples that energy exists in several different forms
What are other forms of energy?

7. What Are Other Forms of Energy?
7 Forms of energy to know
Mechanical – motion of object
Sound - vibrations
Nuclear – fusion and fission
Thermal – temperature of object
Electrical – batteries or power lines
Electromagnetic – visible light, microwaves
Chemical – food, cells in your body, matches
