Question

Is Energy A Physical Thing?

Answer 1

1. Energy is a resource that is transferred from one system to another.
2. Energy is the capacity of a system to do work.
3. If one system applies a force to another system over a long distance, it has done work. When this happens, energy moves from one system to another.
4. During this process, at least some energy is also converted from one type to another. The amount of energy entering or leaving the system can be monitored.
5. The combined potential and kinetic energy resulting from the motion or current state of physical objects is known as mechanical energy.
6. Physical bodies have kinetic mechanical energy, which is half the product of their mass and the square of their velocity.

Hence, energy is a physical thing.
