No matter how much horizontal velocity a projectile has, it still falls at the same rate. Back to Ch. 3 questions. The center of mass is the average position of the mass of an object. Back to Ch. 3 questions. Hint Angular velocity is the rate at which an object spins.
Angular acceleration is a change in angular velocity.
Specifically, it is the change in angular velocity divided by the time interval for the change. Back to Ch. 3 questions. Hint Rotational inertia is the rotational equivalent of inertia. Back to Ch. 3 questions. Hint A torque is a twisting action that causes a change in rotational motion.
