Work, Power, Kinetic Energy
... Work is a scalar quantity, although the force and displacement involved in its definition are vector quantities. 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 ...
