When potential energy and kinetic energy are added, it creates:
a. chemical energy
c. mechanical energy
b. thermal energy
d. electromagnetic energy?

c. Mechanical energy

Explanation:

Mechanical energy is the sum of potential energy and kinetic energy.

Mechanical energy is the energy that an object has because of its movement velocity or its specific position. And this energy can do a certain Work.

If we had an object with certain mechanical energy and this object is in an ideal environment, that is a place where there are no other acting forces to take energy from the object, then the energy will always be constant.

But if we have the object in a place that there are other conditions then we start losing kinetic energy and gaining potential energy. Because mechanical energy is constant, we never lose or gain mechanical energy, we only lose or gain potential or kinetic energy.

And this is equal to the equation:

Ek + Ep = Mechanical Energy.

If the kinetic energy goes down then the potential energy has to go up to keep with the same relation.
