126.96.36.199.188.8.131.52 To find theta between two elastic collisions, use
184.108.40.206.1.3 To find velocities, we use relative velocity trick, (v2 − v1)f = −(v2 − v1)i
220.127.116.11.1 An inelastic collision is one in which part of the kinetic energy is changed to some other form of
energy in the collision.
2.1.1 M= Kg
2.1.2 V= M/s
3 Angular Momentum= L
3.1 Vector quantity
3.1.1 Moment of Inertia - Kg x meters^2
18.104.22.168 The rotational analog to mass- it represents an objects rotational inertia. An object's rotational inertia is determined by the chosen axis of rotation and is additive.
22.214.171.124.1 Parallel axis theorem: The moment of inertia of a parallel axis is equal to the moment of inertia of an object's center of mass + the total mass x the distance between the center of mass and the parallel axis of rotation
