Question

A body of mass m is moving with a uniform velocity. A force is applied on the body due to which its velocity changes. How much work is done by for e

Answer 1

Hummm.. e is here it you know

Power is Force*Velocity

So, energy or work done is integration of POWER.

Force*Velocity integrated in perspective of FUNCTION OF TIME.

so, in easy base we have,

Force *velocity*dt.   ( dt, as change is much small to be integrated.)

So, here we get,

Power*dt=Force*distance as work done or energy consumed due to certain force dissipation.
