Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass of the object and its velocity.
Work-Energy Theorem: This theorem states that the work done on an object is equal to the change in its kinetic energy.
This principle states that in a closed system where no external forces act, the total momentum before and after an event remains constant.
Rotational kinetic energy refers to the energy possessed by rotating objects. It depends on their moment of inertia and angular velocity.
