Question

write the expression for work done by a force...Plz tell fast.. ​

Answer 1

Answer:

HELLO

Work done on an object along a given direction of motion is equal to the force times the displacement times the cosine of the angle. No work is done along a direction of motion if the force is perpendicular.

(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.

hope it helps you mate.
