Question

define work. how is work measured

Answer 1

Work is said to be done only when the force applied on a body makes the body move i.e.,there is a displacement of the body
If a force acts on a body and the body does not move then no work is done
W=F x S where F is force and S is displacement . By this work can be measured

Answer 2

work is defined as the product of force applied and displacement .work is measured as Joule or J...
formula for finding out work = F * s
work is a scalar quantity ...
