25 дек. 2018 г. · Usually, the term impulse means the difference in momentum: →J=Δ→p. Force is the time derivative of momentum: →F=d→pdt⇔d→p=→Fdt.

10 июн. 2014 г. · F=dp/dt follows directly from F=ma and the definition of mechanical momentum p=mv. F=ma is validated ultimately by experiment.

15 февр. 2014 г. · Impulse is caused by force, and therefore separate to momentum. Impulse causes a change in momentum -- it isn't the change in momentum itself.

2 нояб. 2024 г. · We call this the impulse of the force. So a large force acting for a short time causes the same change in momentum as a smaller force acting for ...

21 сент. 2014 г. · 1) In classical mechanics, impulse is the product of a force, F, and the time, t, for which it acts. The impulse of a force acting for a given ...

4 янв. 2017 г. · The time derivative of momentum is force, not impulse. Impulse is the time integral of force. – Ghoster. Commented Dec 24, 2022 at 23:50.

18 сент. 2022 г. · In classical physics, the formal definition of the impulse is the integral of the force, 'F' over a certain time period t. Mathematically, it ...

12 сент. 2024 г. · Hence, having two equivalent formulae helps you finding the impulse when you have one variable (momentum, force) and not the other. Share.

4 нояб. 2014 г. · If the rate of change is instantaneous, the derivative is infinite, and the force is infinite. There are no infinite forces.

19 мар. 2015 г. · Yes, in that instance impulse equal momentum, since impulse equals change in momentum. ... Impulse as the time derivative of force · 0 · Impulse ...
