"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.

One end of a spring with a force constant of k = 10.0 N/m is attached to the end of a long horizontal frictionless track and the other end is attached to a mass m = 2.20 kg which glides along the track. After you establish the equilibrium position of the mass-spring system, you move the mass in the negative direction (to the left), compressing the spring 2.03 m. You then release the mass from rest and start your stopwatch,...
