Answer:
Explanation:
Given
Force (F) = 20 N
Displacement (s) = 1 m
Angle between force and displacement θ = 60°
★ Work (W) = Fs cos θ
= 20 × 1 × cos 60°
= 20 × 1 × ½
= 10 J

Explanation:
The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.
