  1. Potential and Kinetic Energy

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

  3. Potential Energy is stored energy. Water behind a dam Hammer over head Food on the plate energy of motion, the form capable of doing work Flowing water A falling hammer Electrons regenerating ATP in a bio’l cell Potential Kinetic

  4. What is Potential Energy? • Energy that is stored and waiting to be used later

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

  6. What is Gravitational Potential Energy? • Potential energy due to an object’s position • P.E. = mass x height x gravity Don’t look down, Rover! Good boy!

  7. What is Elastic Potential Energy? • Potnetial energy due to compression or expansion of an elastic object. Notice the ball compressing and expanding

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

  9. What is Kinetic Energy? • Energy an object has due to its motion • K.E. = .5(mass x speed2)

  10. Kinetic Energy Energy of a moving object

  11. 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! What is Mechanical Energy?

  35.  1. Daniel designed the above house. However, when he built a model of the house, he realized that the weight of the second story made the ceiling of the first story sag. What could Daniel do to fix this problem? A. add columns to the design of the first story to hold up the weight of the second story B. add more rooms to the second story C. make the outside walls stronger D. put an elevator in the house rather than a stair case 2. Cho is using technological design to build a clock based on the apparent motion of the Sun. Which of the following would be the best measure of success for Cho's clock? A. The time shown on Cho's clock is eleven hours ahead of the actual time. B. Cho's clock is small enough to be worn as a wrist watch. C. The time according to Cho's clock is very similar to the actual time. D. Cho's clock works even at night. 3. Sandra is creating a new piece of technology. Her teacher has provided the following steps for designing new technology: 1. Identify a problem or need 2. Design a solution or a product 3. Implement the chosen design 4. Evaluate the solution or the product Which of the following should Sandra do during the evaluation step? A. generate ideas on how to solve the problem efficiently B. build and test the solution or product C. gather information on the problem and possible solutions D. determine if the new solution or product solved the problem
