For the front unit, we always use mass point to study an object. In this unit, we will use an ideal model - rigid body. It is a model with mass and volume. In the same time, we will compare rotation and translation motion.
Angular displacement
- comparing angular motion to linear
Torque
Angular Momentum
Angular Impulse
Rotational energy
Different object have the same mass, which one touches the ground first?
