​Your answer is wrong!
Well Probably...

If you said anything regarding school work, then you are wrong! Because (by the physics definition) "mental work" is not work.

​Work = Force x Distance

By Newton's 2nd law, we know that it takes a force to change the motion of an object.

We also know that Impulse = Force x Time, so work is kind of like the distance version of impulse.

No Movement, No Work

You can push on a brick wall as long and as hard as you want, but if it doesn't move, you technically haven't done any work.

Work is measured in Joules (J), which is Newtons x Meters

So 1 Joule = 1 Newton of force applied for a distance of 1 Meter

Power = work/time

It is harder to do work quickly then it is slowly, and this is where power comes in. It takes more power to push a box quickly across the floor, than it does to push the same box the same distance across the floor more slowly.

Power is measured in Watts. One watt (W) of power is consumed when one joule of work is done in one second. One kilowatt (kW) equals 1000 watts. One megawatt (MW) equals one million watts.
