Let’s just admit it. Most of us hate our jobs. Only about 31% of Americans feel “enthusiastic about and committed to their work and workplace”. Even for people who work at something they enjoy, the idea of doing it for 8 hours a day, 5 days a week, for the rest of our lives can feel like an early death sentence. Sweden has decided to do something about it. In keeping with their history of progressive social policy, Sweden has begun to shift to a 6 hour work day, with many of their largest…
One of the most beneficial attack strategies in volleyball is the execution of a fast paced, downwards directional spike. A spike is proven to be one of the most effective shots in volleyball due to its force and difficulty for the opposition to return the shot. Through developments in modern technology in sport, biomechanics has become one of the most influential evaluative sources for skill analysis aiding improvements in sporting performance. A video analysis of my volleyball spike will be…
of the force of gravity. Gravity is a force of attraction between two objects, that is highly affected by size and proximity (gravity will have a stronger pull if the object are larger and close together). Gravity also differs from the mass of an object the more mass an object has the more gravity it will exert on the objects around it. When looking at really large masses, like the earth the gravitational pull becomes much greater because of its large mass. The earth's gravitational force pulls…
This experiment, created by the students of the class, went relatively well. In this lab, we teste the theory of the conservation of energy. The kinetic energy at the bottom of the ramp should equal the potential energy at the top of the ramp without regard to the path taken. Thus, for method 1, the equations for kinetic energy (1/2mv²) and potential gravitational energy (U_g=mgh) were used. For the second method, the concepts and formulas for constant acceleration was used in conjunction with…
Script Are reusable rockets a sustainable possibility for the future? What are rockets? Rocket technology is extremely wasteful, and being a one shot wonder, they show no promise of a sustainable future. When a rocket is launched, it is propelled based upon newton’s 3rd law of motion; “For every action, there is an equal and opposite reaction.” This is done by using on board propellant which is then used to create thrust from a rocket engine, by ejecting thrust in the opposite direction to…
As these two forces are equal and opposite, the resultant force is equal to zero, and by Newton’s first law, the handle remains at constant motion resulting in no feeling of ‘shock’ in the hand. The next point of interest is the vibration node. Using terms from wave theory, the node is…
used during these processes includes adrenaline, which is also referred to as apinephrine. Adrenaline is produced by the adrenal glands, and is responsible for the immediate reactions a person would feel. Another important hormone is norepinephrine, coming from the adrenal glands and the brain. Norepinephrine makes a person more aware and awake, shifts blood flow, and is the backup system for adrenaline. Lastly, is the hormone cortisol, which takes more time to be released into the bloodstream.…
Relaxation Therapy Everyone has gone through a time where they feel stressed, especially if you are a sophomore nursing student dealing with the pressure from all of your classes on top of the rest of your busy life. Although small amounts of stress can be a good thing, too much of it can lead to a negative impact on your health. Some may experience physical and mental symptoms such as muscle tension, increased respirations, hypertension, stomach pain, decreases or increased peristalsis,…
Stress What is stress? Stress is what your body feels when you’re faced with a situation that you can’t handle in a proper manner, or when you feel threatened. Reading the aforementioned definition, one will realize that we encounter stressful situations on a daily basis. After procrastinating for a week, you decided to complete your assignment just before it’s due by a few hours. The anxiety and panic you are feeling is the result of stress. You are going to pick up your fiancée, as you are…
