AP Physics 1
Unit 3 – Circular Motion and Gravitation
Topic 3.2
When describing the forces between an electron and a proton, we use electromagnetic forces instead of gravitational forces because
Gravitational force doesn't act on small particles like electrons
There is no gravitational force on the electron and proton.
Opposite charges results in cancellation of gravitational force.
The electromagnetic force is much stronger than the gravitational force.
