This is not correct. Compare with the case of a clump of clay with some velovity hitting another stationaty piece of clay and sticking together. Is the kinetic energy the same before and after?MITPhysics said:
Angular momentum is a measure of an object's rotational motion, calculated by multiplying its moment of inertia by its angular velocity.
A large wooden turntable can increase the moment of inertia of an object placed on it, which in turn increases its angular momentum.
The angular velocity and the moment of inertia of the object are the main factors that affect the angular momentum. The friction between the object and the turntable can also play a role.
Angular momentum is conserved on a large wooden turntable because the turntable itself does not exert any external torque on the object, so the angular momentum of the object remains constant.
Yes, angular momentum can be transferred from the turntable to the object if there is a change in the angular velocity or moment of inertia of the object. This can happen through external forces such as friction or when the object is lifted off the turntable.
