Detailed Solution

The kinetic energy of a body depends on velocity as v2
The energy possessed by a body by virtue of its motion is called its kinetic energy. The amount of kinetic energy can be measured by the amount of work done by the object before it comes to rest. Kinetic energy not only depends on the motion of the body but also depends on the mass of the body.
The formula for kinetic energy is KE=12×m×v2 So, from the formula, we can observe that the kinetic energy depends on velocity as v2
