1) What kind of energy is gained when your roller coaster goes uphill?

2) Based on your observations, what is the relationship between potential and kinetic energy?

3) If friction was completely removed from the track, what affect would this have on the roller coaster ride?

4) 4) Why does the number of carts matter when designing a roller coaster track?

(Hint: PE = mass x gravity x height and KE - ½ mass x velocity ^2)

The answer for the first question - increasing of potential energy (as a result of the gravitation field)

The second : when the roller coaster gets upwards it becomes slower a bit and while potential energy is being increased, the kinetic one is getting lower. Do not forget that the sum of these energies is always constant.
