Onservative forces are present, does all of the energy in a system remain in a usable form?

5. When non-conservative forces are present, does all of

Explain.

6. What type of force are the force of gravity and the force exerted by a spring? How does this type of force

influence the energy in a system?

7. As an object falls to the ground, what happens to its energy? Ignore air resistance in this scenario.

8. If air resistance acts on a falling object, will all of its potential energy be converted into kinetic energy?
