Course Description
The motion of particles and rigid bodies is illustrated using linear, rotational, and plane motion. These concepts are used to determine the forces and torques required to change motion through inertia, work-energy, and impulse-momentum approaches. Other important concepts include elastic and inelastic impact, power, and the coefficient of restitution.
