Instantaneous Angular Acceleration: Instantaneous angular acceleration refers to the rate at which an object's angular velocity changes at a specific moment in time. It can be calculated using calculus by taking the derivative of the angular velocity with respect to time.
Centripetal Acceleration: Centripetal acceleration is the acceleration experienced by an object moving along a curved path due to its change in direction. In rotational motion, centripetal acceleration acts towards the center of rotation and keeps objects moving along their circular paths.
Torque: Torque measures how effectively a force causes an object to rotate or twist around an axis. It depends on both the magnitude of the force and its distance from the axis of rotation.
