Weight Lifting

## Tug of war with Bailey

I have a dog named Bailey and she's 3 years old. She's a golden retriever Rottweiler mix, so her and I often play tug of war! She'll grab on to one end of her rope and I'll whip her around with the other end. I realized that there s actually a lot of physics involved in this! Both me and Bailey are pulling on the rope and creating tension. If both Bailey and I pull on the rope and the ball doesn't move, keeping it in the same position despite our pulling, that means that the amount of force in e

## The Whirlwind

For many years as a kid I would often go to Seabreeze Park and I enjoyed going on rides. This summer I also was able to work at Seabreeze. One of my favorite rides there has been the Whirl Wind. There is a lot of physics behind how this roller coaster works. First off as ride reaches the top of the first hill it begins to accelerate down the hill. It starts with a slower velocity and then gains speed as it goes down the hill. The twist in the ride(see what I did there) is that as the cart goes,

## The Physics of Wrestling

Wrestling is a very fun sport that I enjoy taking part in. It takes a lot of work, however it is completely worth it and it is very fun. There is a lot of physics taking place in wrestling. One example is when two wrestlers are in neutral or standing position. While wrestling the two wrestlers when fighting for hand control will often be banging heads or putting pressure on each others' foreheads. The force that one applies on the other will always be the same as the force that the head applies

## The physics of football

One of my favorite things to do with my friends over the summer is play pickup football. There is a lot of physics that is involved in playing the game of football. First off when the quarterback throw the football to a receiver he must apply a force to the ball so that it can travel in the air to the receiver.Whatever force he applies to the ball, the ball then applies back onto his hand. Once the ball is in the air its horizontal velocity should stay about the same(neglecting air resistance).

## The physics of baseball

I've been able to play baseball for many years of my life and was able to some over the summer in a town league. There is a lot of physics involved in the sport of baseball. For example in baseball the pitcher has to throw a pitch to the catcher while the hitter tries to swing. The ball is thrown at a very fast horizontal velocity. that stays fairly constant neglecting air resistance. The ball however still drops at an acceleration downward of 9.81 m/s^2. There is also a lot of phys

## The physics in me dropping my phone

Over the summer I was playing basketball with some of my friends. We had decided to take a break so I was walking around and looking at my phone. While I was walking my friend took a shot and air balled, knocking my phone out of my hand causing it to fall and smash the screen on the driveway. There was a lot of physics involved in this sad occurrence. First when my friend shot the ball, once it was in the air gravity started pushing down on the ball with an acceleration of 9.81 m/s^2. This i

## Spring Break Surfing

This spring break I'm getting to flying down to Florida to visit my friend Aaron! Aaron is a big surfer so while I'm down there I'm going to get to learn to surf along with him. With break now approaching, i figured it would be a good opportunity to look into a little bit of the physics of surfing! First there is a lot of basic application such as the fact that the force that the board exerts on the water, is exactly equal to the force the water exerts onto the board. However as a researched mor

## Physics in drivng

Recently on Wednesday I was a able to drive quite a lot which used a lot of physics. One example, is when I merged onto 104 I needed to increase my speed so I did so by acceleration. I accelerated increasing my velocity in the far right lane until I finally reached about 55 mph so I could merge on in between cars. Increasing and decreasing speed or velocity is a very important aspect of driving. Another aspect is the force exerted between the car and the road. All of the cars mass is exerted ont

Another sport that enjoy playing in my free time with many of my friends is basketball. There is a lot of physics involving forces in the game of basketball. One of the most important aspects of the game is dribbling. To dribble a player must push down and apply a force on the ball so that it hits the ground with another force. Next the ground pushes a force back onto the ball which causes it to bounce back up to the player. Whatever force the ball exerts on the floor as it is dribbled, is the s

## Isaac's Blog

One activity that i do in order to stay in shape when not in wrestling season is lift weights. Lifting actually involves quite a bit of physics. For example when you use the bench press you need to apply a force on the bar to push up the bar and the weights that are on it. The amount of force you exert on the bar is the same amount the bar exerts on you. Also, the reason for why the weights feel heavy is from gravitational force pulling the weights downward at an acceleration of 9.81 m/s^2. In a

## Go Karting

When I was in Jacksonville I went to a go kart place called the Autobahn Indoor Speedway. These weren't your typical go karts however. At the Autobahn the cars reached speeds up to 50 mph! Drivers have to wear helmets for safety and the speed made for some pretty intense races. There was a lot of physics involved in driving the cars. One of the most important parts of learning how to be as fast as possible was getting used to knowing how much and when to brake around turns. Braking too much will

## Dodgeball

This past Sunday I was able to play dodgeball in the Dodge For Josh tournament. With our team being American themed, we were The Star Spangled Ballerz. It was very fun and after I played I realized that there was a lot of physics involved in our dodgeball games! The first thing I noticed is how the ball would dropped whenever I would throw it. Part of this is due to air resistance that slowed the ball down, but most of is from gravity pulling the ball down. Neglecting air resistance, gravity sho

## Clay Shooting

Over spring break I was able to go down to Jacksonville, Florida to visit my friend Aaron. While I was there we decided to go clay shooting at a shooting range with his dad's shotgun. It was both helpful and interesting to understand a little bit about how the physics if the bullets when they shot. First off, it is helpful to know that the velocity of the bullets once shot out, always stay the same horizontally. Neglecting air resistance, the velocity should stay exactly the same. However gravit

## Catapult Project

Creating my Catapult for class with Mike Belmont and Kelan Graham involved a lot of physics. One objective we had was to make sure our softball launched at a 45 degree angle to maximize the distance traveled. Our design was a ogre catapult so we realized to make a 45 degree angle we needed to make the distance from our pole the flinger rotated on to the front of our blocking device needed to be equal to the distance from the top of the base up to where the flinger hit our blocking device.
