Answer:
the eqation is W = F × D × cos(Θ)
Explanation:
example
A 100 Newton force is applied to a 15kg box in the horizontal direction and moves it 5 meters horizontally. How much work was done?
In this case, we know the force is 100 N and the distance is 5 meters. We also know that since the force is applied in the same direction as the displacement, Θ is equal to 0. So we plug these values into our equation
W = F × D × cos(Θ)
and get:
W = 100(5)cos(0)= 500 J
So, the 100 N force did 500 joules work moving the block 5 meters.
