  1. Section 2: Kinetic Energy & Potential Energy Lockheed Martin completes final test flight of its hyper-velocity kinetic weapon

  2. Kinetic Energy = Energy of a moving object KE = 1/2mv2 Sample Problem: Find the KE of a moving car with the following parameters

  3. Conceptual Question: To increase the KE, is it better to increase the mass or speed and why?

  4. Work Kinetic Energy Theorem A fellow pushes a 1000kg car with 20N for 5 meters. Find the cars kinetic energy?

  5. Gravitational Potential Energy (PEg) PEg = mgh

  6. Elastic Potential Energy (PEe) PEe = 1/2kx2 Find the Following: Elastic Potential Energy stored in the band if it is pulled back .5 m and has a spring constant of 50N/m 2) KE of the rock right after it is shot: 3) The total potential energy of the system if the rock has a mass of .05kg and is 1.3 meters high when shot. 4) *** how fast is the rock traveling when it hits the ground?

  7. Mixed Problem • Find the kinetic energy of a 1000kg car that is traveling 30m/s? 2) If the same car is to coast up a hill, how far can it vertically make it? 3) How far must a sling shot be pulled back to have the same energy as the car in problem number one of it has a spring constant of 90N/m?
