Hi,
I am trying to solve one problem of circular motion and I searched on Internet and found many things and I am confused about different forces or I think same force is shown as different symbol. What I learned is as follows:Force = F = ma (horizontal movement - where height is not involved)
Force = F = mg (vertical movement- where height is involved -circular/rotational motion)
Centripetal Force = Fc = m*ac (circular or rotational motion)
Normal Force = Fn or T or N = Fc + mg (circular or rotational motion)
Normal Force = Fn or T or N = Fc - mg (circular or rotational motion)
Sometimes there is also Fnet, Fg used. Or might be different site or man explaining uses different symbol for same force. Can someone please explain. Fg is I think gravity force and that's already calculated somewhere like mg or m*ac. So other than standard gravity force and frictional force I am confused.
Mine problem.
I want to calculate which forces are working on roller coaster at top and bottom in 100% unified circular motion. I am not student but my project is exactly like roller coaster i.e. object/mass moving in vertical circle. I want to calculate how much net force is acting on top and how much on bottom. So can find power according to force value.Shaks
