When you’re upside down at the top of a vertical looping roller coaster, why is the centripetal force acting on you the least of anywhere in the loop?
In: Physics
“Angular velocity” is how fast you’d be going if the track was straight, which basically is what tries to keep you going forward but the track is turning you.
Your “angular velocity” is the slowest at the top because that’s when it starts to pick up speed again because of gravity. So then the speed of the track trying to turn you is the least at the top, which is another way of saying your centripetal force is the least at the top.
Assuming for a perfect circular track.
