Question

what is the definition of energy in scientific terms?
the motion of an object
the ability to do work
a change in temperature
a force used on an object

Explanation:

Energy is defined as the ability to do work. Work is done when a force causes an object to move. The motion of an object (kinetic energy is a form of energy related to motion but not the definition of energy itself). A change in temperature is related to thermal energy transfer. A force used on an object is just a force, not energy. Energy encompasses various forms (kinetic, potential, thermal etc.) and the common thread is the ability to perform work.

Answer:

the ability to do work
