Question

Is it possible that a body be in accelerated Morin under a force acting on the body yet no work is done by the force? explain with examples

Answer 1

yes, of course... , if the body isn't displaced , it isn't considered as work done!

for example, a car has started from a initial point,a and travels for about 100 kms under accelerating motion , and gets back to the iniatial position a , then

displacement=0

so, work done =0
