What is a easy problem to solve for potential energy?
For example, an easy problem is just to calculate the potential energy (by multiplying mass x gravity x height). Some things you can do to make it slightly more complicated include:Give some of the data in different units (height in cm, or even in non-metric units; mass in pounds, or gravity on other planets or moons).Instead of figuring out the potential energy, take the potential energy as given, and work out one of the other three variables (height, mass, or the gravity of an unknown planet).
