**January 10, 2012 Potential and Kinetic Energy** 1. You need the weight of the car and the height of the ramp to find the potntial energy of the car at the top of the ramp.2. 3. Potential energy = .02016 Joules 4. We will need to measure the car's mass and its velocity. To find the velocity we need to find out how long it takes for the car to go down the ramp and the length of the ramp. To find the mass we'll use a triple beam balance. 5. 6. Kinetic energy = .01548 Joules 7. Percent difference = 22.21428
