Question

Which of the following statements most accurately differentiates potential and kinetic (a)kinetic energy is a form of mechanic energy,while gravitational potential is not.(B.)any object that has motion has kinetic energy, while any object not in motion but with the potential to do work has potential energy.(C)gravitational potential energy is a form of mechanical energy, while kinetic energy is not.(D)any object that has motion has potential energy, while any object not in motion but with the potential to do work has kinetic energy

Answer 1

(B), since that is an accurate definition of kinetic and potential energy
Hope this helped out :) 

Answer 2

The kinetic energy is related to the motion. Hence, any object which is in motion will have kinetic energy associated with the object and an object at rest will have zero kinetic energy.

Any object which has a potential to do work in the future has potential energy associated with it. For example: A compressed spring has potential energy stored in it and it gets converted into the work by keeping an object in front of it.

Hence, the option B is correct.
