Conceptual Question 6.15 Part A Explain why this shape gives a more comfortable ride than a circular loop Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Variation in your apparent weight is desirable when you ride a roller coaster, it makes the ride fun. However, too much variation over a short period of time can be painful. For this reason, the loops of real roller coasters are not simply circles like (Figure 1).A typical loop is shown in (Figure 2). The radius of the circle that matches the track at the top of the loop is much smaller than that of a matching circle at other places on the track. ResetHelp minimum The radius of the loop decreases as the carts enter and exit the loop. The centripetal acceleration is for larger radius loops and for smaller radius loops. increases Figure 14 of 2 larger This means the centripetal acceleration from a at the entry to the loop smaller to a at the top of the loop and then as the cars exit the loop. This prevents a sudden change of acceleration, which can be painful a portion of the trip a whole trip This also limits the largest accelerations to the top of the loop, so that riders experience the maximum decreases acceleration for maximum Submit My Answers Give UpExplanation / Answer
centripetal acceleration = v^2/r
a] smaller, b] larger,
c] increases, d) minimum e) maximum f) decreases
g) a portion of the trip
