How do we know if kinetic energy is 0?
The energy can neither be created nor it can be destroyed as per the principle of energy conservation. However, the feasibility of various events taking place in our surroundings pertains to energy in different forms which are possible due to energy conversions. Some examples of energy types are potential energy, kinetic energy, thermal energy, electrical energy, etc.
Answer and Explanation:
The kinetic energy of a body is exhibiting the zero value when it is at rest. The body is at rest can only be defined if we are able to define our frame of reference. Therefore, if the body is at rest in the frame of reference of consideration then its kinetic energy is zero.
