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 […]
Numerical Problems on Rolling motion, Torque, and Angular Momentum (worksheet with medium & Hard problems)
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 […]
