    High School Normal force on bottom box when top box is heavier

    could you still explain exactly why the small mass on bottom still has 2mG of force to the top? my physics teacher is pretty bad and I've never dealt with normal force problems that involved more than one object (i.e rollercoaster on track. box on slope, etc)

    High School Normal force on bottom box when top box is heavier

    the same. for some reason the rest of the test was pretty easy and this problem had other factors (constant velocity elevator, so no worries) that didnt affect the problem so i got all nervous and thought it was a exceptional case.

    High School Normal force on bottom box when top box is heavier

    I took a practice Ap Physics test today and did well, but there was a basic problem that hung me up: there are two boxes on the ground on top of each other. the top box's mass is 2m, and the bottom's is 1m. question: just looking at the bottoms box's normal force, does it equal the 2m box on...
