How to do you work out force?
Force = Mass x Acceleration (f=mxa)

What is friction?
Friction is a force that opposes motion. It acts when two or more surfaces slide past each other.

How do you calculate resultant force?
The resultant force is calculated by adding together all the forces that act upon an object. Dividing these forces will not give you a useful value.
