Skateboarding is a fun olympic sport you want to learn. Let me teach you. The first person that made it is Larry Stevenson. He made the first skateboard in 1950 in California. How to play and gear. They are in a pit and do lots of tricks. If you have the coolest trick they win , the gear you need is just a helmet or no helmet. This sport is in the olympics. Now are you going to want a skateboard I am!
Newton’s 1st law. An object in rest stay at rest an object in motion stay in motion unless acted upon by an outside force. What are balanced force is when force come together and they don’t move. You are putting force on the skateboard so it can move. The skateboard is at rest you need to put presher on the skateboard so it is No longer at rest. Friction Is a thing Is you were on a skateboard you can slow down you can turn and slowdown and you use your foot. Pushing a skateboard the skateboard is addressed. the skateboard is a moving because you push on the skateboard.
Newton’s 2nd law says that force equals mass times acceleration. How can the skateboarder know how fast or slow the skateboard is going to go you push soft it goes slow if you push hard it goes fast and push is force.
Newton’s 3rd law is action and reaction. It applies into my sports the action is the skateboard goes forwards and the reaction is my foot goes backwards. To stop you slide your foot forward and the board goes backward.
