gravity and acceleration

[Squish miss]

say you have a ball rolling down an incline then it hits the floor
where is the acceleration greater?
this is a general concept but it is when it is in free fall. because at an include plane, the acceleration is less cause of the normal force. can someone explain this intuitively and mathematically?

I'm terrible at explaining things, but if this is specifically the type of question you think you'll be asked in the MCAT, I used this site for maths prep: Numerical Tests: Test Training
