Question

How is work done by a force measured when :
1)force is in direction of displacement.
2)force is at an angle to the direction of displacement.

Answer 1

Answer:

work done = force * displacement

in the case of (1)

work done = force*displacement cos thetha

in the case of (2)

hope it may help

Answer 2

Answer:

F.S=Work

Explanation:

Since equation of force is F.S=FSCosθ

for case 1. θ= 0 therefore work = FS

for case 2. θ= θ work= FScosθ
