The Main Idea
Energy Diagrams are extremely useful for analyzing the interactions between two different objects. These diagrams can also be confusing if not properly understood. This page serves as a resource on how to construct and interpret energy diagrams. Let's get started!
A Mathematical Model
A Computational Model
Vpython is great for modeling this concept. Using vpython, we can model many different systems that have kinetic and potential energy. We can model a spacecraft orbiting the Earth, and we can create graphs to display the kinetic, potential, and kinetic+potential energies of this system. See this code for how to do this!

Examples
See end for solutions to all examples.
Simple
Label K, U, and K+U on the energy diagrams for the following situations:
Example 1:
Two electrons are held at rest some finite distance apart, and they move away from each other after they are released. Their initial velocities are zero.
Example 2:
A proton and an electron start out far apart. Their initial velocities are nozero, and their energy is repulsive.
Example 3:
An electron has just enough energy to escape from a hydrogen atom.
Middling
Label K, U, and K+U on the following energy diagrams. THEN, label the following three energy graphs 1, 2, or 3 based on the following scenarios: 1: One of the components of this energy diagram is incorrect. 2: A proton and a electron are at rest, and they start out infinitely far apart. 3: A spacecraft orbits the earth.
