If we're interested in the mag. of a projection of one vector onto another...(ie: pulling a wagon, where the direction is horizontal), we can use our formula for projections or components
Work: The magnitude of a force applied to anobject causing a displacement of the object
measured in Newtonmetres or Joules a scalar quantity (no direction)
ex think of the wagon.... is the applied forceis the displacementis the angle between them
