Hey, our names are David and Robin :)

Questions We Have
What position should you be in to have the least drag and go the fastest?
What are some tricks that relate to science?
What science is in snowboarding? ~
How do you stop when you are going fast? ~
How does wind effect you in snow boarding? ~


Research Notes for David
- The wind can throw you into the air and it can blow snow off the trails and uncover ice. It can also speed you up and slow you down.
- Your height, weight and ability are all used to determine a snowboard for you.
- When you snowboard on snow the friction cause by the board on the snow melts the snow so you are sliding on a thin amount of water.
- Bend your knees and lower your self to have less drag and wind resistance so you go faster.
- You bend your body forwards or backwards to turn, you can also bend your feet fowards and backwards turn, too.
- You move your back foot forward and lean back a bit to stop.

Research Notes for Robin

- The height of the wall can help the boarders go higher as it leads to more "potential energy" being stored by the athlete before take-off.
- While gravity is the determining factor in the maximum attainable velocity, factors that can reduce frictional influences and air resistance will allow the rider to get as close to this value as possible. From this maximum velocity, the rider must maintain a sufficiently high level of control to retain the ability to maneuver and direct the board for the ride.
- A snowboarder starting their ride down the halfpipe has potential energy. Potential energy is stored energy in an object. As a snowboarder moves down the side of the pipe, potential energy gets converted into kinetic energy. The kinetic energy of an object is the energy it possesses because of its motion. When they jump, the kinetic energy is converted back into potential energy. Gravity slows them down in the air, so they lose kinetic energy. At the height of their jump, the snowboarders are at their maximum potential energy.
- To slow down and turn, a boarder 'digs' into the snow with their riding edge and leans in the direction they want to move. The larger amount of snow and the force of gravity create a set of forces whose net force push the board in the direction desired by the rider.
- Probably the most fundamental physical property in snowboarding is simply keeping the center of gravity over the riding edge. Any time an objects center of gravity moves beyond the base which keeps the object up, the object will fall.
- The board moves quickly down the hill because it is lubricated by the water present in the snow. When the board is placed on top of the snow, the contact between the snow and board creates friction which melts a small amount of water.
SHAUN WHITE
- He will rely on gravity to supply this external force to his skateboard or snowboard. To get started, Shaun pushes off the ramp's ledge. Then, gravity pulls on his board and he starts speeding down the ramp, says Paul Doherty, a physicist at the Exploratorium in California. The speed Shaun gains by cruising down the ramp is critical for winning contests. The faster he goes, the higher he will fly when he launches off the ramp's opposite side--and the more points he will score with the judges.
-Another factor that influences how high Shaun soars is the height of the ramp. Half-pipe ramps are nearly 5 meters (15 feet) tall in skateboarding and 12 m (40 ft) tall in snowboarding. The taller the ramp, the more gravitational potential energy Shaun will store at the top of it. When Shaun pushes the nose of his board down the ramp, that stored energy gets converted into kinetic energy sending him whizzing down the slopes
- Whether Shaun is doing flips on his snowboard or catching big air on his skateboard, he relies on Newton's first law of motion for every trick. This law states that Shaun will remain at rest unless acted upon by an outside force
