Force is mass times acceleration same as F= m x a ; this means a object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass.
The momentum and impulse states that the change in momentum of an object is equal to the impulse applied to it. the equation for this one would be; F= m x a same as the force and acceleration equation.
I don't know if this really helped, but I tried my best so hopefully you get it, if not tell me I will try to explain it more. :)
