energy and work
Consider an object that travels from point A to point B while two constant forces F1 and F2 are exerted on the object. Note that the forces have unequal magnitude and F1 is directed toward point A and F2 toward point B.
a) Is the total work done on the object by F1
positive, negative or zero?
Is the speed of the object at point B greater than,
less than or equal to the speed of the object at point A? Explain.
What is a "conservative force"?
What are some examples of both conservative and non-conservative
If we have a conservative force, how can we related
the work done by that force to the potential energy stored in the system?
