How does the mass of an object effect the amount amount of force it takes to move the object?

I would say directly...the bigger the mass the bigger the force you need:

Explanation:

We can summarize the idea using Newton's second law:
#F=ma#
Ok, this is very simplified but in essence it gives us the idea. You want to move an object that is you want to give an acceleration #a# so rearranging:
#a=F/m#
You see that to move an object, say from rest, if you increase the mass the force has to increase to maintain our acceleration.

For example: if you want an acceleration of #10m/s^2# for an object of mass #m=5kg# you need a force:
#F=5*10=50N#
If you increase the mass to #10kg# the force has to increase to:
#F=10*10=100N# to still have an acceleration of #10m/s^2#.
