Question

Where is the kinetic energy present in the body and its use?

Answer 1

Kinetic energy is the energy associated with the movement of objects. Although there are many forms of kinetic energy, this type of energy is often associated with the movement of larger objects. For example, thermal energy exists because of the movement of atoms or molecules, thus thermal energy is a variation of kinetic energy. However, most of the time, kinetic energy refers to the energy associated with the movement of larger objects. Therefore, if an object is not moving, it is said to have zero kinetic energy. The kinetic energy of an object depends on both its mass and velocity, with its velocity playing a much greater role.

Examples of Kinetic Energy:

1. An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.
