Golf
This is a little bit of information about golf. It originated in scotland. It first appeared in the Olympics in paris. In the year 1900. The stuff you need are a golf bag and a driver. The irons wedge a sand and putter. It's played on a golf course. The rules are you can't move the ball with your hands. You can only have 14 clubs at most. If it goes out of bounds. It subtracts one from your score. Next I'll tell you about Newton's first law.
This is how Newton's first law is in golf. First I'll tell you what his law is. Objects in motion will stay in motion unless acted on by an unbalanced force. Objects at rest will stay at rest unless acted upon by an unbalanced force. Second, I'll tell you what an unbalanced and balanced force is. A balanced force is when an object has two forces that keep it in place. An unbalanced force is when one force is stronger than the other causing an object to start or stop moving. Now I'll give you an example of a balanced force in golf. A balanced force is friction and gravity after you hit it because eventually the ball will stop and be balanced. Now I'll give you an example of an unbalanced force. When you use muscle force to hit the ball with your club the muscle force makes the ball move so it's unbalanced because it's moving. I'll give you an example of an object at rest. The golf ball is at rest when it's sitting on the golf tee because it's not moving. Now I'll give you an example of an object in motion. Like when you hit the ball and it’s moving through the air it’s in motion because it's moving. The ball on the golf tee will no longer be at rest when it's moved by the club. The ball will stop being in motion when gravity and drag force bring it to the ground where friction and drag force stop it.
Newton's second law is f=mxa or force =mass x acceleration. It's a form of calculating speed. What is force here's an example. In golf when you use muscle force when you swing the golf club. Friction is another force but it stops stuff instead of moving it. Now I'll tell you what mass is. It’s matter the more matter something has, the more mass something has. Like a golf ball it's easy to throw but if it hits a wall it will slow down and stop. But a bowling ball is hard to start moving but it's even harder to stop it. Acceleration is when something speeds up. You might not know this acceleration is also when something slows down acceleration is a change in speed or direction. Like when you swing the club it accelerates through the air. Then it hits the ball and gravity pulls it down where it accelerates or decelerates. If you use a lot of force the ball will accelerate quickly. If you don't use that much force it will accelerate slowly. If you use a lot of force on something with a lot of mass it might not accelerate as much. But it won't be stopped as easily. You need to predict how much force you need to use. You don't just figure it out from the distance you need to take drag as a possibility. Drag is when the wind slows something down or moves it. Also friction can affect your shot. So golfers mostly estimate the amount of force needed.
This is Newton's third law. Every action has an opposite reaction. An action is something you can do. Like swinging a golf club. The golf club will go up and back over your shoulder. Your shoulders will go forward and down. Then you will swing the club at the ball. You may not feel it but the ball pushes the club backwards. Then the ball sours through the air its opposite reaction is pushing against the air particles. The ball goes down and hits the ground its opposite is it bounces up in the air again. When the ball falls in the hole that has an opposite to. It bounces instead of sinking in the plastic. It moves it away instead of letting it misshapen the plastic. That's Newton's third law in golf.
