Explain why a thrown football has both potential and kinetic energy. what is the combined energy called?

The combined energy is called as mechanical energy.

Explanation:

Kinetic energy is the energy possessed by the motion of the object.

Potential energy is the energy which is possessed by the location of the object.

The combination of both these energies forma a different type of energy known as mechanical energy. Mechanical energy is the energy which is possessed by both motion and location of the object which is used to do work.
