Answer:
Zero work is done when a vertical force acts on an object moving horizontally
Explanation:
Word is the dot product of force and displacement.
W = F . s
W = Fs cosθ
θ is the angle between force and displacement,
We need to find how much work is done when a vertical force acts on an object moving horizontally.
That is angle between force and displacement = 90°
θ = = 90°
Substituting
W = Fs cos90 = Fs x 0 = 0
Zero work is done when a vertical force acts on an object moving horizontally
