"The work done on a system by an agent exerting a constant force on the sytem is the product between the component of the force along the direction of motion and the displacement of the object under the application of force."
W=(F cos (theta))d
W= (f)(d)cos (theta)
Work is scalar
The visual used is "A box moves a distance, "d", under the action of an applied constant force, "F" that makes an angle theta, with the direction of motion." The vertical is Fy= F sin (theta) and the horizontal is Fx= F cos (theta), with the horizontal going in the direction of the movement.
Can someone explain this in a another way? This information comes from a lecture on "work." I am awful at physics and have very little understanding of the subject thus far.
