Cite an example in which a force is exerted on an object without doing work on the object

Sagot :


The classic example is pushing on a brick wall as hard as you can.
No matter how hard you push on it, the wall is not going anywhere.

Since
            Work = (force) x (distance),
and  
           distance = 0,
it turns out that
           Work = (force) x (0)  =  0 .
