When teaching the skill of sweeping or brushing to novice curlers necessary to always remember the three basic fundamentals. These fundamentals are body weight, brush speed and footwork. Throughout the process of teaching our skill we will continue to highlight these fundamentals ensuring that our teens will remember them and hopefully demonstrate them as they continue to curl. During our teaching of the skill it is important to note that we will always be watching for unsafe practices on the…

Energy comes in many forms, and can be converted from one form to another. Kinetic energy is energy of mass in motion, and the formula is E=1/2mv^2. The most important property of kinetic energy in the ability to do work, and it can be transferred from one body to another in collision, which can be elastic or inelastic. Joule found out about Energy and made joules by looking at a falling weight that was twisting a pole making temperature. Before and after, energy has to be conserved and stay the…

Introduction Section- The purpose of this experiment is to use reaction stoichiometry to determine the molar mass and the identity of an unknown, powdered metal, and to identify an unknown metal nitrate solution. To give a little background information on this experiment I will start by saying that a balanced chemical equation provides several important pieces of information about a chemical equation. Those important pieces include the substances consumed and formed, the physical states of the…

Lab 3: Technology Name: Section: General Physic Lab 3 Date: 10/03/2017 Purpose The goal of this experiment was to learn how to apply computerized instruments in physics. In addition, this experiment aimed at enhancing practice on how to use three equipment in the lab: the rotary motion sensor, high resolution force sensor, and motion sensor. Further, this experiment sought to clarify the circumstances under which the instruments fail to comply with expectations. Results/Data Part 1: The…

inside and with all the sponge to absorb all the shock from the fall, and a box on the outside to prevent the momentum from crushing the egg inside the sponge, which left the egg intact. The design of the vehicle could have been improved to reduce weight, and increase the security of the egg inside the sponge. A majority of the natural force that would have affected the egg was expected, things such as, momentum, gravity, air, and the ground were the egg was going to fall on. The egg was dropped…

The Magnet Cannon is a perplexing object to understand how the forces work, in this explanation I will explain how the forces and energy in the magnet cannon work. The purpose of the magnet cannon is to help show how kinetic and magnetic forces work. The magnet Cannon is an object composed of 5 balls a ruler and a magnet. One of the balls is placed on one side of the magnet (ball A), then the other 4 balls (balls B-D) go on the other side of the magnet, then the contraption is placed on a ruler.…

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…
