Newton’s three laws of motion essay Isaac Newton was an English physicist, mathematician, astronomer, and natural philosopher who lived in the 17th century. One of his accomplishments was coming up with three laws of motion that can be used to explain how and why stuff move. These laws that Newton came up with are still used today. Newton’s first law of motion states that “an object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it”.…

In the photo, a baseball is being hit by a bat in a game. This photo was taken at a Gonzaga baseball game on campus (I used a profession photo because they are way better and a second photo is used to show the moment of contact which is what I am talking about). In terms of the physics in the photo. The focus of this paper will be on the energy transfer from the bat to the ball, which causes the ball to reverse directions, increase velocity, and create a launch angle to potentially be a…

Projectiles, such as the ones shot from cannons, are affected by drag or air resistance. The amount of drag exerted on to an object is affected by many different factors, such as air density and the size of the projectile. It is important to understand drag, as it affects the distance an object is able to travel if it is not influenced by outside forces, such as a cannons projectile. The equation for drag is shown below. F=pCA/2 v^2 p = The density of the air. C = The drag coefficient of the…

Roller coasters are a must see attraction in amusement parks around the world, even though they are a good source of entertainment not many are aware of how roller coasters actually function. Even though each and every roller coaster is unique all of them work under the same concept. Most roller coasters start out by ascending to a higher surface which is done to build up enough potential energy to power the carts throughout the entire ride. Energy is usually defined as the ability or…

The Archers Paradox What is it? Have you ever heard the term “Straight as an arrow”? Well, this isn’t exactly accurate. Arrows don’t exactly fly straight, they twist and bend as they fly. When you draw back and release your bowstring the large force of kinetic energy stored in the limbs gets transferred into the arrow and this force causes the spine of the arrow to start bending as it gets pushed forward. The archer’s paradox is this bending of the arrow around the bow as it is being loosed…

Have you ever wonder what the difference IS between a longboard and a skateboard? You will learn the many differences and similarities between the two. First I will tell about the Skateboard, A skateboard is 28.5 inches in length and 7.5 inches in width. It has small wheels only measuring at 2.04 inches wide. The wheels are designed for short travel and traction. Because of this that means it isn't made for cruising like a longboard. The average truck size for skateboard is 6.5 inches in…

Crash Analysis: The analysis of crash in this case will look at the speed of the vehicles, braking and any line of sight issues. Conservation of Linear Momentum Speed analysis in this case is determined by the use of several speed equations. The first equation is the use of the formula Conservation Of Linear Momentum. (COLM) COLM requires knowledge of the vehicles weights, approach and departure angles and post collision speeds of the vehicles. The vehicle weights were determined in this…

1. Describe a roller coaster design that the cart was not able to travel through safely. There was only a few things that would make a roller coaster design dangerous for the cart. One example would be how pointy the angle was for of each hill. The more pointy the hills, the more dangerous the landing of the cart would be. Another example would be the height of the loop of the roller coaster. The loop should be high enough so that the cart could travel with more energy. 2. Describe a…

recognized that his first law needed some additional explanation because most of the motion we observe around us undergoes changes and is the result of one or more applied forces; therefore, Newton wrote a Second Law of Motion which relates force, mass, and acceleration. Newton's third law of motion is often called the law of action-reaction. In the most basic definition of a force, it is a push or a pull. Newton recognized that a force was actually an interaction between two objects; example,…

PACE Speech The problem I researched for this experiment was to see if the weight of a ball affects the speed that ball in travel at when shot or thrown. While researching this I found out that many different sports involve arm strength to throw an object far or at high speeds and many athletes don’t have enough arm strength or maybe don’t have much at all, but for every sport there is always a workout plan to increase what is needed. To increase your arm strength, the weight of a ball is a…
