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…

Objective: The purpose of this lab was to examine Newton 's second law by observing the relationship between force and acceleration in a friction-free environment and to illustrate the concept of mass. The experiment was conducted in such a way to reduce friction. In order to simulate this environment an air-cushioned track was set-up for the glider to ride on a pocket of air without being in contact with the metal track. In addition, this glider will have masses attached to it as well as a…
