Back toGame

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 …
