When a constant force is applied to a body moving with constant acceleration, is the power, of the force constant ? If not, how would force have to very with speed for the power to be constant ?

Explanation

We know that power (P) = force (F) `xx` velocity `(upsilon).` Since the body is moving with acceleration, `upsilon` changes and as a result of that P also changes, F being constant. For P to be constant, `F upsilon` = constant or F `prop 1// upsilon` Thus, as `upsilon` increases, F should decrease to keep P constant.
