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…
Waking up in the morning knowing that you have a corporate job working from nine to five must be the best feeling ever right? If your job requires you to stay after your eight hour shift, the time in a half pay for overtime must be nice too. Well not everybody has the luxury to say the same. As we know in the United States, most of our everyday products that we use are made overseas. Most of what we buy is from developing countries and is grown and manufactured by workers whose rights were…
Analysis/Discussion: This graph above shows that different heights does affect the speed of a shuttlecock. On the x axis, the data is the height of where the shuttlecock is dropped from, while the y axis is the average speed (m/s). The height where the shuttlecock is dropped increases, as the average speed of each height increases as well. The result of the graph is shown that the line keeps on increasing even if it is not a straight line graph. These results support my hypothesis, which states…
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…
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…
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…
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…
