Question

You are on a roller coaster and enter a loop, traveling on the inside of the loop. You pull positive Gs. What provides the centripetal force to make you move in a circle?

Answer 1

Answer:

While traveling on the inside of the loop, you will pull positive Gs and acceleration provides the centripetal force that pushes you against your roller coaster seat.

Explanation:

Due to acceleration, centripetal force keep roller coasters on their tracks and people in their seats. Centripetal force points to the inside of the loop and the car needs to travel fast in order to apply enough centripetal acceleration the roller coaster entering the loop.

When the cars are on the track, gravity pulls downward at a constant magnitude, but as it speeds up almost at the top of the loop, it and the track add together with the centripetal force.
