No they don't. The force of the water against the front of the jet ski will stop it when you slow down. :)
No hills
They use a ski-lift. The ski-lift pulls them up-hill - against the force of gravity until they reach the top of the run. They then ski back down the slope.
Ski lessons are where you learn to ski.... At mine we skied down a hill, walked it up sideways, did the "Pizza", and learned how to stop. Basically you just learn how to ski.
Ski wax lets the skis glide over snow.

There are several ways to force an car engine to stop. One way to force the engine to stop is to disconnect the battery. Another way to force the engine to stop is to turn off the ignition.

That force is called an Opposing Force.
It takes less force to stop a train than to stop a car.
