Show that power force × velocity
WebShow the power = force × speed. Hard Solution Verified by Toppr Since power is measured of how energy changes over time we can write P= tW Since W=F.D(force×displacement) Work = energy by the work - energy theorem So P= tF.D displacement/time=velocity P=F.V Hence proved Was this answer helpful? 0 0 Similar questions
Show that power force × velocity
Did you know?
WebP = d W d t. If the power is constant over a time interval, the average power for that interval equals the instantaneous power, and the work done by the agent supplying the power is W = P Δt W = P Δ t. If the power during an interval varies with time, then the work done is the time integral of the power, W = ∫ P dt. W = ∫ P d t. Webuse the following equations: work done = force × distance moved in direction of force. change in gravitational energy = mgh. power = work done time taken, power = rate of energy transfer. power = force × velocity. efficiency = useful energy transferred total work done × 100 %. understand changes in the way that energy is stored before and ...
Web2 Answers Sorted by: 1 Power is defined as P = F ⋅ v where F is the driving force and v is the velocity of the moving object. In this case, determine the values of both F and v, and use this to calculate the power. If you need additional help, feel free to ask in the comments.

Webtest mass at A(x). Now, power = force × velocity. But we don’t want the net force on A(x), only the force from the left to compute power transmitted. We calculated that the force from the left is F =T ∂A ∂x. For ∂A ∂x >0 this force pulls downward. To see the power transmitted, we need the force which moves the string away from ...
