fast twitch fibers. “They are better at generating short bursts of strength or speed than slow twitch fibers”(Quinn). Fast twitch fibers helps vertical jumping the most because for a vertical, one will need to burst into the air quickly with a lot of force. Slow twitch fibers give more energy for extended workouts such as running a marathon(Quinn). For a vertical, slow twitch fibers are not as important as the fast twitch…

over time. What worked for us humans a few thousand years ago may not be as helpful today? So while our behavior adapts to the changing times and environment, it is thought that it never completely forgets its evolutionary roots. One of the driving forces of some human behavior is something called the “fight or flight response” (also known as the acute stress response). This is the psychology term that describes one of the ways we can react when under stress. Understanding the purpose of the…

Football Position: CDM (Centre Defensive Midfielder) Strength 1 = Power Within my chosen activity of football I believe that power is one of my biggest strengths. Power is the ability to exert maximum muscular contraction instantly in an explosion burst movements or in the least amount of time possible. The two components of power are strength and speed. E.G. jumping for a header, sprinting to the ball. Power is needed to jumping for header because you need power for your take-off into the air…

middle of the ramp. This would keep times from increasing due to obstructions on the surface of the slope. The initial velocity of the trolley was kept consistent throughout trials by letting the trolley roll down on its own rather than applying force to it by pushing it downwards. This kept the initial velocity from changing throughout trials and allowed the results to be as accurate as…

It is amazing what we can do to our bodies to relieve stress. The hustle and bustle of our everyday lives make stress inevitable. Interestingly, the ear massage has been proven to be quite effective when it comes to treating various ailments. An ear massage is an easy task which you can perform at the comfort of your home or office. This is a technique that should be done daily so as to provide efficient results in the long-run. Moreover, there are different massage therapies to treat medical…

sensitive component in an altimeter or barometer that measures absolute pressure of the air. -Sealed, flat capsule made of thin corrugated disks of metal soldered together and evacuated by pumping all of the air out of it. PRESSURE – amount of force acting on a given unit of area and all pressure must be measured from some known references. BAROMETRICSCALE/KOLLSMAN WINDOW- small window in the dial of a sensitive altimeter in which the pilot sets the barometric pressure level from which the…

experiment, we use the mass of an object as an independent variable to come to a conclusion about force and acceleration. By increasing the mass of an object at an incline, one can observe the change in acceleration and furthermore determine the net force acting on the object. With several calculations and graphs to illustrate our results, we shall strengthen implications of the relationship between force, mass, and acceleration. Introduction Mass is defined as. Acceleration is defined as…

Air also has two similar properties, mass and elasticity. Stiffness and elasticity are interchangeable quantities as both possess the same features. A spring is a highly elastic object which can be displaced from equilibrium through applying a force to the mass. This is generally done by compressing or stretching the spring. By compressing the spring, the spring is displaced from equilibrium and moved towards the right, automatically assigning a sense of direction causing negative…

Daniella Vidaurreta Physics April 8, 2015 Isaac Newton Isaac Newton, also known as one of the best mathematician and physicist of all time. Newton was born into a poor farming family and lost his father three months before being born. In 1661 Newton was sent to Cambridge University and began studying mathematics. Soon after, Cambridge University broke out in a plague causing everyone to evacuate. Through out the plague years of 1665 and 1666 Newton made the most significant discoveries…

expand the concept to the process involving several constant forces and the process involving variable forces. After introduce the concept of kinetic energy, we will show the transformation between energy and work. Finally we will generalize these concepts to any system going through any process that involves energy and work and elucidate the fundamental concept of energy conservation. 5.1 Work The work that we are talking about is what a force produces during a process of moving an object. Two…
