Question

Momentum and collision simple questions

Answer 1

My question is, basically mass has a play in both the velocity and momentum, the heavier the mass the slower the velocity and momentum, so basically mass has an impact on the momentum correct? like if there were 2 tucks and they were-both going the same speed, one of the trucks is filled with heavy bricks, this would make it a larger mass. if the truck with bricks in it is heavier than the truck without, then the truck with bricks would take longer to slow down than the one with out. So im asking if the mass is larger than the momentum would be slower?

Answer 2

I think I got your question, correct me if I am wrong.
First of all mass does not have a role in velocity. Velocity is distance per unit time.
Therefore only distance and time has a role in velocity.

Yes Mass has role in momentum, Momentum = mass x velocity.

You said that the truck with heavier bricks will take more time slow down compared to the lighter truck. This is as you said, when velocities are constant.

Looking back at the momentum equation, M = m x v.

So if velocities are same, The comparison of momentum is only on mass.
So for the heavier truck, the momentum will be greater compared to the lighter truck.

So greater the momentum, greater the force required to slow the vehicle.


Hope I helped.

i understand now thanks!
