what happens to acceleration as you change the mass or the forces involved?
it has to due with newtons 2nd law of motion... help!?
does it increase, decrease? i don't know lol!

F = ma
a = F/m
a is proportional to F
a is inversely proportional to m

The relationship here is Force = momentum/time but given momentum it is
Force = Mass*velocity/time which is Force = mass * acceleration or F = ma.
So this can be rearranged for a as acceleration = Force/mass so as the mass increases if the Force stays constant then the acceleration decreases. And if the Force increases and mass stays the same the acceleration increases.
It makes sense if you think about it, it is harder to move something that is heavy, something that has more mass, so a greater force is needed for the same acceleration.
