This might make it sound like on force causes the other, but this isn't true. The forces either exist together or not at all.

You are probably familiar with for every action, there is an equal and opposite reaction, but let's simplify it. All forces come in pairs that act on different objects, are equal in strength, and act in opposite directions.

The force of A on B is equal in magnitude an opposite in direction of the force of B on A.

F_{A on B} = -F_{B on A}
