Chapter 7: Conservation of Mechanical Energy in Spring Problems
... The previous example involved essentially just one particle, the car. The wall was fixed there as a device for exerting a constant force during the collision. A more complex example can be studied when two particles collide. We first make the approximation that the two particles are subjected to no ...

Roller Coaster Project Write Up
... Gravitational potential energy is the energy an object has as a result of its position in a gravitational field. Based on the mass of the marble, the height of the position, and the gravity (9.8m/s^2), the GPE differs throughout the roller coaster ride. When the marble is going down the incline, the ...
