Projectile: When the snowboarder is in the air, he is a projectile. He’s flying through the air, with gravity being the only force applied to him.
Acceleration Due to Gravity: This occurs when gravity is the sole force acting on an object. It causes the object to accelerate back to earth at a rate of 9.8 m/s/s or 10 m/s. When the snowboarder ascends into the air, he would never descend without the help of gravity.
Friction: Friction is the force that opposes motion.Half pipe snowboarders want less friction between the board and the track because friction slows them down. When their speed decreases, they can’t jump as high, leaving them with less time to do tricks.
Kinetic Energy: As the snowboarder moves back and forth on the track, he has kinetic energy. Kinetic energy is the energy of an object in motion. Going down the halfpipe, the snowboarder has kinetic energy the entire time, except for when he is at the top of his jump.
Potential Energy: When The snowboarder is at the very top of his jump, he changes out of kinetic energy and into potential energy. Potential energy is the energy of an object at rest. As the snowboarder begins to to descend, he switches back to kinetic energy.
Instantaneous Speed: Speed at any given moment in time. When the snowboarder goes up the ramp his speed is 40 mph. When he ends his runs he's only going 5 mph. You could do instantaneous speed for any point during the snowboarders run.
The Law of Conservation of Energy: This law states energy can neither be created nor destroyed, only changed or transferred from one object to another. While the snowboarder is in the air he has potential energy. As he hits the ground, he has kinetic energy. Here, energy switched from potential to kinetic.
Force: One of the forces applied to a snowboarder is torque. Torque is the force that rotates an object. Torque allows the snowboarder to spin and flip in the air.
Newton’s 2nd Law: Newton’s 2nd law states that mass and acceleration are inversely proportional. This can be applied to snowboarding. When the same force is applied to two snowboarders of different masses, the larger snowboarder accelerates at a slower speed, while the smaller one accelerates at a faster speed.
Newton’s 1st Law: Newton’s 1st law says that an object in motion stays in motion until acted on by an opposing force. When the snowboarder launches himself up into the air, he will continue to fly upward until an unbalanced force, in this case gravity, overcomes it.

FACTS ABOUT SNOWBOARDING 1. Snowboarding has been around since the 1920s. 2. It was inspired be skateboarding, skiing, and surfing. 3. Snowboarding was introduced to the United States in the 1960s. 4. It became a Winter Olympic Sport in 1998. 5. Modern snowboarding began in 1965.
FACTS ABOUT SNOWBOARDING (con) 6. The International Snowboard Federation was founded in 1990 to make the universal rules. 7. There are many different types of snowboarding. 8. A few types in the Olympics include the freestyle, half pipe, slalom, etc. 9. Snowboarding was the fastest growing sport in the year of 2000. 10. The first snowboard was designed by Sherman Poppen.
As crazy as it seems, there is some math in snowboarding. One equation involved in snowboarding is F=ma (f-force, m-mass, & a-acceleration.) So, as a snowboarder travels downward after his jump, he is traveling at a speed of 10 m/s squared. This is acceleration due to gravity and this number will always be the exact same. Continuing, if he is traveling at 10 m/s squared and he weighs about 75 kilograms we can figure that he needs 750 Newtons to travel down the slope.
Another math equation in snowboarding would be d/t=v. "D" stands for distance, "t" stands for time, and "v" stands for velocity. So, if a snowboarder travels 180m (length of the half pipe) in 12 minutes, we can figure out his velocity. We just plug in the numbers. (180/12=15 meters per minute). However, this may not be accurate due to the fact that the snowboarder probably changed speeds as he did tricks.
Gravitational Potential Energy is energy an object has because of its position in a magnetic field. To get GPE, you have to multiply mass, gravity, and height. Let's use 70 for mass, 10 for gravity, and 3 for height. If you multiply them all together you'll get 2100 Joules of energy.
