Which statement best defines energy? energy is the force applied over a distance. energy is the ability to do work. energy is the rate at which work is done. energy is the motion of objects.

Energy is the ability to do work.      

Explanation:

Energy is the ability to do work. There are many types of energy like kinetic energy, potential energy, thermal energy, chemical energy, nuclear energy etc. In any work, the total energy of the system remains conserved as per the law of conservation of energy. It states that,

Kinetic energy + potential energy = total energy

So, the correct option is (b).

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure
