Thank you.
-
@KeiUKtv mg (Weight of the car.) = Fn ( The force pushing upwards on the car.)
-
@cooleeme If the car is not floating and it's not sinking into the ground they should be equal in force.
-
Which has greater magnitude? The normal force or the weight?
-
@mangaka08 ooooo the force of inertia is pushing u down, then the normal force pushes u up, but since you're upside down, the normal force is down?
-
@Luuuuuuuuuuuuulz Because the normal force is pushing in the opposite direction when the track is upside down. If you were on top of the track, the normal force would be pushing you up, but if you're below the track, it's still pushing you "up", but your new "up" is now downwards.
-
hey, why is there a normal force going downward at the top of the loop? :S
-
I see you're married....truthfully ANYONE in my school would marry you.
cause damn, you help me pass my tests
-
what if you wanted to find it at some arbitrary point along the circle...not the top/bottom
-
So clearly. Thank you alot

No. For each situation you have to figure out the net force by drawing the free-body diagram.
