Compelled VS Coercion

What is the difference between compelling someone to do something, versus coercing them to do something?

I looked up the usage and definitions in order to better get a handle on my own thoughts and how they need to be expressed.

An action that is compelled seems to be done in response to outside factors, but mostly done on a voluntary basis. Duty Compels.... etc.

Coercion on the other hand is use of force to compel actions.

Is it tyranny to force an individual to provide their skill, labor, goods, and/or services?
