2. Potential and Kinetic Energy

3. How is all energy divided? Potential Energy Kinetic Energy All Energy Gravitation Potential Energy Elastic Potential Energy Chemical Potential Energy

4. Potential Kinetic energy of position or energy in storage. Water behind a dam Water behind a dam Hammer over head Hammer over head Food on the plate Food on the plate energy of motion, the form capable of doing work Flowing water A falling hammer Electrons regenerating ATP in a biological cell

5. What is Potential Energy? oEnergy that is stored and waiting to be used later

6. Potential Energy The energy in matter due to its position or the arrangement of its parts

7. What is Gravitational Potential Energy? oPotential energy due to an object’s position oThe higher an object the greater the gravitational potential energy oP.E. = mass x height x gravity height x gravity Don’t look down, Rover! Good boy!

8. What is Elastic Potential Energy? oPotential energy due compression or expansion of an elastic object. Notice the ball compressing and expanding

9. What is Chemical Potential Energy? oPotential energy stored within the chemical bonds of an object

10. What is Kinetic Energy? oEnergy an object has due to its motion oK.E. =.5(mass x speed 2 )

11. Kinetic Energy Energy of a moving object

12. What is Mechanical Energy? o Energy due to a object’s motion (kinetic) or position (potential). The bowling ball has mechanical energy. When the ball strikes the pins, mechanical energy is transferred to the pins!
