Here we are asked to draw the free body diagrams of m1 and m2.
00:09
So looking at our problem, let's do a rough recreation.
00:14
You have a mass m2 of this incline and mass m1 here, and there is a force applied at m2.
00:26
So let's take a moment to write out the free body diagram of each.
00:32
So let's draw m1 over here.
00:35
So suppose m1 is kind of angled off as pictured in our problem.
00:42
So of course we're going to have our force of gravity.
00:46
Call that f1g, or sorry, i'll call that actually, let's call it the gravitational force.
00:59
The gravitational force fg1.
01:03
And we also have the normal force, which is being essentially being caused from this m1 block onto the m, excuse me, m2 block onto the m1 block.
01:16
And we also have the force of static friction here.
01:22
That's helping keep this block from sliding down...
