Gravity and Orbits
... •For circular orbits, there is a simple relationship between the potential energy and the kinetic energy: •For non-circular orbits, this is not true, because energy keeps changing between the two components. •However, if you average over time, this will still be true ...

Since the cars have equal mass and approach each other
... c) Assume the cars have equal mass and suppose instead of sticking the cars bounce off from one another elastically. What now will be each car’s final speed? Explain your result in terms of impulses and the forces each car exert on one another. (5) As we have seen and discussed in class when the car ...

Physics of Rolling Ball Coasters
... We will now consider the energy of the system. The system is closed, so energy must be conserved. Set the reference point for potential energy such that the ball starts at a height of h. Initially the ball is at rest, so at this instant it contains only potential energy. When it has traveled the dis ...
