Question

fill in the blank question consider a simplified model of your motion while on a circular inversion loop of a roller coaster where it is assumed that your speed around the loop is consta the bottom of the track, the direction of your acceleration is

Explanation:

Step1: Recall centripetal acceleration concept

In uniform - circular motion, centripetal acceleration $\vec{a}_c$ points towards the center of the circle.

Step2: Analyze position at bottom of loop

At the bottom of the circular track of the roller - coaster loop, the center of the circle is above. So the acceleration points upwards.

Answer:

upwards
