Linear velocity refers to the rate at which an object moves in a straight line, while angular velocity refers to the rate at which an object rotates around a fixed point.
Angular velocity is calculated by dividing the change in angular displacement by the change in time. It is typically measured in radians per second.
The moment of inertia is a measure of an object's resistance to changes in its rotational motion. The higher the moment of inertia, the slower the object's angular velocity will be for a given torque.
Linear and angular velocity are related by the distance from the axis of rotation. The linear velocity of a point on a rigid body is equal to the angular velocity multiplied by the distance from the axis of rotation to that point.
Yes, linear and angular velocity can change independently in a rigid body. For example, if a car is driving in a straight line and then turns, the linear velocity of the car changes while the angular velocity of the wheels also changes.
