No, the WORK is the same

No, No, No...
Are you another one of them physickists or mathemagicians that don't know the difference between energy and power?

The Work done is exactly equal to the Kinetic energy.

Kinetic energy = 0.5mv^2 = Work = F x distance = m x accel x distance

Power = Work / time

You go a longer distance but the acceleration is lesser, and the Work is the same.

No need for erroneous clutter--do you want to delete your post, then i'll delete mine...
