Calculating Thrill Ride Velocity Using Potential and Kinetic Energy

Click For Summary
SUMMARY

The discussion focuses on calculating the velocity of a thrill ride by utilizing the principles of potential and kinetic energy. It establishes that the initial velocity, along with the height of the hill, allows for the determination of velocity at various points during the ride. The conversation also highlights that g-forces alone are not sufficient for this calculation unless the radius of the turns is known, as they act perpendicular to the direction of motion.

PREREQUISITES
  • Understanding of potential energy and kinetic energy principles
  • Knowledge of basic physics concepts related to motion
  • Familiarity with g-forces and their implications in motion
  • Ability to calculate velocity using height and energy conversion
NEXT STEPS
  • Research the equations for potential energy (PE = mgh) and kinetic energy (KE = 0.5mv²)
  • Learn about the relationship between g-forces and circular motion, including radius calculations
  • Explore examples of thrill ride physics in engineering contexts
  • Investigate simulation tools for modeling ride dynamics and energy conversions
USEFUL FOR

Physics students, amusement park engineers, and anyone interested in the mechanics of thrill rides and energy transformations.

I have a question. Would it be possible to calculate the velocity of a thrill ride at any given time, given the rate of change in g-forces and the velocity of the ride at the start (or if there's a hill at the start, the velocity of the car going uphill)?

Using the height of the hill, you can calcuate the velocity at any other known height by converting potential energy to kinetic.

G-forces won't help you with anything because they are perpendicular to the direction of motion...unless you have the radius of the turns.
