Media Image
FIGURE shows an object placed on a table. It is observed that normal force, N and gravitational force, mg both do no work to the object. This is because
W=Fs cos θ and θ is 90°, hence work is zero
W=Fs cos θ and θ is 0°, hence work is zero
W=Fs sin θ and θ is 90°, hence work is zero
W=Fs sin θ and θ is 0°, hence work is zero
