A box is pushed across a rough horizontal surface. What happens to the potential energy of the box?

A block slides down a ramp with friction. How does the work done by friction affect the potential energy of the block-Earth system?

Potential energy is a...

How does changing the relative positions of objects within a system affect the potential energy of the system?

Why is the zero point for potential energy considered arbitrary?

A spring with a spring constant of $k = 100 ,\text{N/m}$ is stretched by $0.2 ,\text{m}$. What is the potential energy stored in the spring?

A spring has a potential energy of $10 ,\text{J}$ when stretched by $0.1 ,\text{m}$. What is the spring constant $k$?

A block of mass $m$ is attached to a spring with spring constant $k$. The spring is compressed by a distance $x$ and then released. What is the maximum kinetic energy of the block, assuming no energy loss?

What is the gravitational potential energy between two objects of masses $M = 6 \times 10^{24} ,\text{kg}$ and $m = 10 ,\text{kg}$ separated by a distance of $r = 6.4 \times 10^6 ,\text{m}$? (Given: $G = 6.674 \times 10^{-11} ,\text{N} \cdot \text{m}^2/\text{kg}^2$)
