... Notice that we can write Eq. (1) either as (F cos θ) × s or as F × (s cos θ). This suggests that the work can be calculated in two different ways: either we multiply the magnitude of the displacement by the component of the force in the direction of the displacement or we multiply the magnitude of t ...
