Question Rate of change im momentum

Good Day,
My name is Rabia. I would like to know he the rate of change in momentum is the same for objects of 2 different sizes if the same size force is acting on it? Can anyone help?

Momentum is mass times velocity, and for objects with constant mass the rate of change of momentum is mass times acceleration. From Newton's Second Law, F=ma, so the rate of change of momentum of an object is equal to the force applied to it. Hence it doesn't matter what the value of m is - the rate of change of momentum is always equal to the force applied.

Thumbs up Rate of change in momentum

Thanks @ChipB that was super helpful. It's my first time on this forum but it's amazing to have such fast results while study for the June exams.
Thanks a mil

Yep.

The derivative (rate of change) of momentum is simply F.

dp/dt = F

actually, $\dfrac{dp}{dt}=F_{net}$
