An object moving in a straight line (having linear momentum) can have angular momentum. For example, let’s say we throw a ball at one end of a stick (see Figure 1). The stick can pivot around point O. When the ball hits the stick, the stick rotates. If the system of the ball and stick has […]

## Angular Momentum, moment of inertia & Rotational motion

In this post, we will discuss a couple of interesting questions related to Angular Momentum, Torque, moment of inertia & Rotational motion. How does angular momentum work in rotational motion? The angular momentum of a rotating object is equal to the product of its moment of inertia and its angular velocity. If there is no […]

## Angular Momentum

When an object moves with an angular speed ω along the circumference of a circular path of radius r, then we say that it has angular momentum. Angular momentum is the rotational equivalent of linear momentum and is defined as the moment of Linear momentum. It depends on 2 quantities, one is rotational inertia or […]
