the apogee might be affected in a variety of ways, one being the weather. After the class found all of the data, it was compared and analyzed for any patterns. The rocket had different forces acting upon it during the flight stages. The first stage is ignition, (when the engine of the rocket ignites) the force acting upon the rocket is the thrust (push/propel) due to the electric launch controller which heated up. After the motor created thrust, it caused the rocket to lift-off (creates…

actually have a positive outcome. Learning that stress can cause individuals to focus better in some situation is a little surprising but also makes me realize I am actually a victim of this situation. Making important life decisions while under stress forces some to quickly think of the positive outcome of the situation. In fact it triggers a risky side in most individuals. “ The increased focus on the positive also helps explain why stress plays a role in addictions, and people under stress…

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…

certain forces are required to move the puck, stop the puck, and accelerate the puck. Also, for every force applied on the puck, there is always an equal and opposite reaction. The next few paragraphs will explain the science of air hockey and how it relates to Newton’s laws of motion. The air hockey tables are the start of it all. The air hockey tables make it capable for the puck to glide effortlessly across the surface of the table. There…

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…

The fight-or-flight response is the reaction when a person perceives a threat. This person has now has two physiological options, to stand up to that threat and fight, or to run away (Grohol). To understand what happens during fight or flight, one needs to understand what chemicals and hormones are used during the process. First, the nervous system is broken down into two major systems: Central and Peripheral. The central nervous system consists of the brain and the spinal cord, and deals with…
