11. Snowboarding & ski jump Snowboarders use gravity to move down the track and increase speed. When they are going fast enough they jump into the air and do tricks before gravity brings them back to the ground. Ski jumpers start at the top of a big ramp. Gravity makes them speed up until they get to the end of the ramp. They fly into the air and try to go as far as they can down the mountain before they land.
