The object which has only kinetic energy is: A. a coiled spring, a stretched elastic band.
Generally, there are two (2) main types of energy and these include the following;
Potential energy can be defined as a type of energy that is possessed by an object due to its height (position or location) above a surface or planet Earth.
Kinetic energy can be defined as a type of energy that is possessed by a physical object (body) due to its motion or a change in velocity (acceleration).
In this context, we can infer and logically deduce that the object which has only kinetic energy is a coiled spring, a stretched elastic band.
