Question 22

Is there a fixed amount of force in the universe?
No, forces generally depend on the distances between objects, so that two objects that are moving together or apart will experience different amounts of force as they move about. As a result, the total amount of force anywhere can change freely. But there are quantities that have fixed totals for the universe. The most important of these so-called "conserved" quantities is energy.
