I was reviewing this problem, and I'm getting confused about what theta is in the equation for W=Fxcostheta
I know it says that theta in this case for the Force of friction and displacement is 180 degrees, but I thought that the angle of the incline corresponded to the angle used in the equation.
If it had asked for the work done by gravity with an increase in the angle of the incline, would it increase? Because the force due to gravity on an incline is
F = mgsin theta, where theta is in...
