Introduction Squirrels are small rodents commonly known across the United States. There are over 200 squirrels species. They belong in the genius Scieridae(1). There size is varies from 5 inches to 3 feet long. The commonly known squirrel in Kansas is either the Eastern Fox Squirrel, its recorded size varies from 18-28 inches. The genus name for the Easter Fox Squirrel is Sciurus Niger(2). Animal activity can be measured in the observation of animals in a certain location. The Activity can…

by an outside force. This law applies to gymnastics when a gymnast is flipping through the air they will not stop flipping until they either hit the ground or change their body position. Newton's second law states that the net force acting on an object will cause it to accelerate (F=ma). Newton's second law applies to gymnastics because male gymnasts are usually more muscular than female gymnasts so the tend to have more mass. This means that they will have to apply more force than female…

deeper detail; the forces acting in play. Newtons Laws govern the central principles regarding the physical forces which may act on a particular object in space. There are three laws which were developed by Sir Isaac Newton in 1686, when he published his book Principia Mathematica Philosophiae Naturalis (NASA, 2015). Newton’s Law One states that ‘Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change to state by forces impressed on it’…

Propulsion is a force that pushes forward or drives and object forward. This concept can be seen in action with the use of a balloon powered car; this car demonstrates a type of propulsion system in which it produces thrust and potential energy and uses the kinetic energy that it will gain from the movement to push the car forward. The thrust is obtained from the balloon which applies Newton’s third of motion that states, “for every action, there is an equal and opposite reaction.” Specifically,…

Goldberg machine is an over- engineered contraption that uses a chain reaction to accomplish simple tasks such as turning on the music, pouring a glass of water, etc. This specific Rube Goldberg machine’s task is to move the last piece on the chessboard to score checkmate by using the most complicated arrangement possible. In this Rube Goldberg machine, an outside source of energy is transferred through the machine when someone adds force to part of the machine therefore starting the “simple”…

The Marine Expeditionary Unit, the basis with which the MAGTF operates, must evolve in the near future in order to cope with the concepts and challenges presented in Expeditionary Force 21. First, refining our organization and adjusting the way we train and fight is necessary to face the ever changing tactics and strategies of our adversaries. Second, our forward posture needs to adjust in order to smartly prepare for crises and hostilities abroad. Nested in these two concepts are several…

mathematics can show us how they interact and how they affect performance. Water Bottle Rockets are mainly used for educational purposes in schools. They are used to explore basic aerodynamics and physics. Water rockets demonstrate many different forces such as weight, thrust, lift, and drag. Basic parts of a common bottle rocket include a nose cone, fins, a base, and a launcher used to launch the rocket. Rocket propulsion started showing up in history around 400 B.C. when a Greek by the…

This law of motion stems off of the idea of force. Simply meaning that when you push off of something, the object that you are pushing off of is going to be pushed back due to the energy it takes to move an object. An example of this is hitting a golf ball with a club. The velocity of the ball is able to change due to the force of a golfer hitting the ball with its club. The more force a golfer uses on a ball, the faster the speed will become. Whereas a slight breeze…

civilisations in Europe and Asia. The ancient game was known as battledore (bat or paddle). Shuttlecock was probably originated more than 2000 years ago in the 1600s, where it was just two people hitting a shuttlecock back and forth without it hitting the ground. In 1934, the International Badminton Federation was formed, with the initial countries, which included England, Wales, Ireland, Scotland, Denmark, Holland, Canada, New Zealand and France. Badminton was introduced to the Commonwealth…

Expeditionary Force 21 (EF21) “provides guidance for how the Marine Corps Total Force – as an integral part of the lager naval and joint team – will be postured, organized, trained, and equipped to fulfill assigned public law and national policy responsibilities.” (Expeditionary Force 21 Capstone Concept p. 5). Expeditionary Force 21 is essentially the Marine Corps 10 year vision and action plan. According Week 1’s video presentation, EF21 seeks to: establish a forward presence of one-third of…
