I study about 3 hours a day just on physics... then I usually have about 5-6 hours of other homework to do so that leaves me with about 5-5.5 hours of sleep a night since I have lab till 4 Monday and Wednesday that means going to bed by about midnight to be up for class at about 6:30 am.

...because he didn't actually teach me any of this and I had to learn basic concepts, like this, all on my own because he can't keep on the same train of thought for more than 1 minute so he never fully develops the full idea we are supposed to be learning.

AKA that's the whole idea of Newton's first law or the idea of inertia. Like if you toss a ball in the air, your hand no longer exerts a force on the ball but gravity acts on it therefore it has to come back down otherwise it would keep going.

So is it true that if you have a constant velocity therefore you have no change in acceleration so A=0 and if you have no acceleration then you have no Fnet? And is that the case in ANY force problem? Thanks!
