State quantitively the differences between electric force, electric field & electric potential.
The electric force describes how a charged particle attracts or repels another charged particle.
The electric field describes the force a charged particle will experience due to its location in space.
Analogy: think of the Earth as a giant electron, and you are a proton. Since you are oppositely charged, you are attracted to the Earth, and vice versa. The electric force is similar to gravity in this manner.
Now think of how your distance from the Earth affects your weight. You know that the farther you are from Earth, the less you weigh, and so the less force you feel. This is similar to the electric field.
A particle's charge is like mass. The E-field is like gravity. The stronger gravity, the more force you feel (due to your weight). The stronger the E-field, the more force a charged particle fields.
