## Newton's Laws of Motion and SnowboardingBy: Maddie voorhees

#### What are the three laws of motion?

1. Law of inertia, an object at rest stays at rest while an object in motion stays in motion with the same speed and direction unless acted upon by an outside force.

2. An unbalanced force causes an object's velocity to change, and the acceleration of an object depends on its mass.

3. Explains action and reaction forces, when an object exert force into a second object, the second object exerts equal and opposite forces into the first object.

#### How are the laws shown in snowboarding?

1st law: Inertia, an example would be when a snowboarder is going to do a trick on a halfpipe and drops in the downhill of the halfpipe carries them enough velocity when they reach the bottom, so that when they come up the uphill part they have enough force and acceleration to do their desired trick.

2nd law: When a snowboarder wants to turn or slow down they must turn their snowboard one way, and turns in the opposite direction.

As you can see in this picture the snowboarder is turning his snowboard and body one way to turn the other way.

3rd law: The third can be best described when a snowboarder collides into another person, or a tree/obstacle. When a moving snowboarder runs into another snowboarder who standing still they will start to be in motion. The action is the first snowboarder running into the second, the reaction would be the second snowboarder starting to move.

#### Force=mass(kg)Xacceleration(m/s2)

Force problem: A snowboarder with the weight of 58.9 kg has an acceleration of 3m/s2. What is the force of the snowboarder? Answer: 176.7 N

#### Momentum(p)=mass(kg)Xvelocity(m/s)

Momentum problem: A snowboarder with the mass of 54.8 kg has a velocity of 7 m/s what is there momentum? Answer: 383.6 P
