Sum of all Forces= Force - Force of Friction(adsbygoogle = window.adsbygoogle || []).push({});

We have Formulas to use in our physics test for an object on an inclined plane w/ friction: Sum of all Froces= F-Ff,

Sum of all Forces=ma,

a=(Sum of all Forces)/m

Ff=Uk(N)

and Sum of all Forces=(mg)sin(theta)-Uk(mg)cos(theta)

We need to know how to derive F (not the sum of forces "F" but the F that is minus Force of friction) if we are only given mass, theta, and coefficient of friction. also We wish to know the difference between weight, mass, mass*gravity, the Normal Force, and Newtons.
