24 авг. 2016 г. · The energy used, understood as the integral of force with respect to displacement (ie work) corresponds to the force (instead of momentum) applied during a ...

21 окт. 2017 г. · Time does appear in the related concept of power (time rate of work: Pavg=W/Δt). So you can calculate Δt, given total W and Pavg.

28 апр. 2019 г. · Work is defined as the line integral of the force because this makes it equal to the change in the kinetic energy.

1 дек. 2019 г. · A time-dependent force f=6t acts on a particle of mass 1kg. If the particle starts from rest, the work done by the force in the 1st second is.

19 сент. 2013 г. · The integral of power wrt time is work done, as I originally said. Power is measured in J/s. Power x Time = Work.

18 июн. 2019 г. · If F is not constant, we can instead say the instantaneous work at any time is δW=F⋅ds; and by taking the integral, we can add up the work ...

12 мар. 2015 г. · The force integral is an integral over a path, with start and end points which become the limits of the integral.

24 мар. 2013 г. · What is the net force? Newton: Fnet=ma=mdvdt. So the net work done to accelerate a particle from v0=0 to final velocity vf is.

6 мар. 2016 г. · By definition, the integral of any force is the work due to that force. ... Why is work done not equal to force times time? 2 · Why is the work ...

13 февр. 2018 г. · You are correct that the force F is ma, where a=(6t−8). The work is the integral of Fdx, with dx=(3−8t+3t2)dt.
