BMX Freestyle
BMX freestyle has a cool background. It started in California in the 1970’s and it got in the Olympics in 2021 in Tokyo. The rules are riders perform as many tricks as possible in 60 seconds as well they’re scored based on the difficulty of the tricks, the height of their jumps as well as the creativity and style. They need safety gear, a bike, and a track. BMX freestyle shows Newton’s laws, too.
Newton’s first law says an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force. Rest is when the athlete is waiting to start at the beginning and stop at the end. Motion is when the player is riding on the bike. Force is when the athlete is putting drag on the bike.
Newton’s 2nd law says the greater the mass of an object the more force the athlete needed to accelerate. Force is when the athlete uses muscles to balance and hold the bike to keep it steady. The gear, bike, and the athlete have mass but if they have less mass they can go faster. Acceleration is when they need to apply force to the pedals to go faster. That is what Newton’s 2nd law is.
Newton's 3rd Law says every action has an equal and opposite reaction. First, the athlete pedals down and back for the action and that causes the bike to go up and forward for the reaction. Second, the wheels spin backwards and cause the bike to go forward. The athlete can also jump up on their bike for the action and then the reaction is that gravity pulls them back down. These are the ways Newton’s three laws are seen in BMX Freestyle.
