1. Kinetic and Potential Energy

6. ME stays the same for bus as it goes down the hill ME = KE + PE The bus at this position on the hill has a very high potential energy and little to know Kinetic Energy PE = weight * height KE = (mass * velocity 2 )/ 2

7. As the bus travels down the hill its PE decreases and its Kinetic Energy is increasing! PE = weight * height KE = (mass * velocity 2 )/ 2 ME stays the same for bus as it goes down the hill ME = KE + PE

8. At the bottom of the hill the bus has very low PE but very high KE PE = weight * height KE = (mass * velocity 2 )/ 2 ME stays the same for bus as it goes down the hill ME = KE + PE
