24 авг. 2016 г. · Since as: v(t)=dx(t)dt. ⟹v(t)dt=dx(t). So: ∫x(b)x(a)mdx(t). Assuming m to be constant, then: ∫bamv(t)dt=∫x(b)x(a)mdx(t)=m[x(b)−x(a)].

8 февр. 2018 г. · The momentum of one particle is not conserved over time, but it should be over all due to the law of momentum conservation.

17 мая 2017 г. · Mass is usually conserved, momentum is usually conserved, energy is usually conserved (assuming there is not net force on the system).

18 янв. 2017 г. · It's the signed area that the line joining the particle and the fixed point sweeps out multiplied by the mass of the particle.

20 февр. 2020 г. · The integral of Fμ with respect to τ is the change in four-momentum. The integral with respect to dxμ, which is the direct relativistic ...

15 июл. 2022 г. · I regard momentum mv as the integral of ma (mass times acceleration) with respect to time, from starting time coordinate t0 to final time ...

19 сент. 2013 г. · If we integrate force with respect to time we get momentum: ∫Fdt=mv. If an object accelerates along a line then we can find its acceleration ...

21 июл. 2023 г. · The initial classical action of interest is: Sinitcl=∫t2t1L(q(t′),˙q(t′))dt′.

16 дек. 2013 г. · Background: Starting from F=ma, integrating with respect to time, and using basic calc, one can derive ∫Fdt=m(vf−vi)
