... Elastic and Inelastic Collisions Momentum is conserved when the external forces are zero or so small they can be neglected during the collision. This is often true. In many collisions a large percentage of the kinetic energy is lost. These are known as inelastic collisions. For example, any collisi ...

... You can also think of the resultant I as Icm + other I’s (specifically, the disks), which is the justification for use of the parallel axis theorem. Picture the Problem. Let x be the radial distance each disk moves outward. Because the net torque acting on the system is zero, we can use conservation ...

... Kepler’s three laws describe the motion of the planets. The astronomer Tycho Brahe (1546–1601) made many precise observations of the planets and stars. However, some of Brahe’s data did not agree with the Copernican model. The astronomer Johannes Kepler (1571–1630) worked for many years to reconcile ...
