@bubbleteddies Because Fn and Fg act as Fc (the force towards the center) so I considered both of them when doing the formula Fnet=mac

Please correct me ...
Please correct me if I'm wrong but I dont think this is correct. Since you're trying to find the minimum speed it must go to offset the loop, shouldn't you consider Fn as a force as well. Fg and Fn are both going downwards so according to newtons second law the equation would be Fg+Fn=ma. Fn must be 0 as that is the minimum to complete the loop, making the equation Fg=ma. Fg=mg and a=v^2/r so the new equation would be mg=m(v^2/r). Masses cancel out so the new equation is g=(v^2/r) making v=7.71

It's weird he talks like any other teacher but his voice keeps me interested, that and the fact that I need to pass physics

can you make a video where speed is not constant (like the car has some kind of force on it) because i get all messed up when the it's changing and i really don't know what to do

Sal; is there any way you could make a video about liquid-liquid centrifugal decanters and how we determine various radial distances from the axis of rotation? Im stuck on these problems and I never get stuck... =o

What about mass? Why wouldn't the force be gravity times the mass of the car?

@LuminaFlux the centre of earth is the centre of the circular path around earth. Just draw it out and you'll see. You'll probably have on of those 'Ooooh, how could I be so stupid'-moment :p

@lolololort To the center of the earth, but not the center of the pertinent loop! Right? Or is this intuition flawed?

@LuminaFlux ...
@LuminaFlux Ofcourse it does. Earth is a sphere and gravity pulls you to its centre..

Take the moons ...
Take the moons revolution around the earth for an example. The earth provides a good inward force for the moon to stay in that path without shifting off the elliptical path its preforming. Its more basic than you think. As for black holes this object will spiral into the black hole I get what you are asking that gravity doesn't make it to be a centripetal force because it doesn't make an object go to the center of the loop, but in this example he used the loop as the circle and gravity as force

How can gravity be ...
How can gravity be considered a centripetal force? Provided that a centripetal force is a force that projects inward to the center of the circle, gravity does not behave this way, right?
