## Rolling Motion of a Rigid Object

Rolling Motion of a Rigid Object. AP Physics C Mrs. Coyle. For pure rolling motion there is “rolling without slipping”, so at point P v p =0. All points instantaneously rotate about the point of contact between the object and the surface (P). v p’ = 2 v cm. Rolling Motion.

## PERIODIC MOTION

PERIODIC MOTION. A repeated vibration or oscillation. Simple Harmonic Motion . Simplest form of periodic motion; it occurs when the restoring force is directly proportional to the displacement from the equilibrium For example, Hooke’s Law: F = - kx Why do we care?

## Conservation of Momentum

Conservation of Momentum. If a system of particles is isolated (no external forces acting on the system) the total momentum of the system is CONSERVED. Consider two particles that are isolated but interact with each other. They start with momenta p1 and p2.

## Sect. 4-8: Friction & Inclines

Sect. 4-8: Friction & Inclines. Friction. Friction is a lways present when 2 solid surfaces slide along each other. We must account for it to be realistic! Exists between any 2 sliding surfaces. There are two types of friction: Static (no motion) friction Kinetic (motion) friction
