Answer:
Step-by-step explanation:
The energy possessed by the body by virtue of its motion is called the kinetci energy of the body.
There are two types of kinetic energy.
1. Translational kinetic energy: The kinetic energy possessed by the body when it is in translational motion. For example, a block is moving on the floor.
2. Rotational kinetic energy: The kinetic energy possessed by the body when it is in the rotational motion. For example, when a wheel is rotating about its axis.
A pulley has rotational kinetic energy if it is fixed as a point.
A rolling body possess both translational and rotational kinetic energy. For example, a sphere is rolling on an inclined plane.
