How many points do you want to risk?
Describe the energy conversions taking place throughout the roller coaster:
Point A to B:
Point B to C:
Point C to D:
At which point is potential energy the greatest and why?
At which point is kinetic energy the greatest and why?
Point A to B: Potential energy to kinetic
Point B to C: Potential to kinetic
Point C to D: Kinetic to Potential
Point A is where potential energy is the greatest because it is the highest hill
and the energy is coming from gravity.
Point C is where kinetic energy is the greatest because it is the lowest point and the car will be moving the fastest
at that point.
And the winner is …
