1. The displacement-time graph consists of a curved line, whose slope is constantly decreasing in relation to time until it reaches a velocity of 0 at its plateau, then continues constantly to accelerate downwards at a constant velocity. The velocity-time graph consists of a straight line which shows the initial speed of the ball when thrown into the air and the final speed when the ball is accelerating downwards. The reason the velocity does not stop at 0 m/s is because the ball traveled past…

In addition, another theorist looked at when the pressure or threat has passed, the stress hormone levels will usually return to normal. However, if you're constantly stressed, these hormones will remain in your body, leading to more severe symptoms of stress (Choices, 2016). Hans Selye’s General Adaptation Syndrome 1936 model (GAS) who was known as ‘the father of stress research’ showed three phases of the alleged effects of stress has on the body. Stress is a major cause of diseases because…

Sir Isaac Newton, born January 4th, 1643, was an English scientist and mathematician, and was the leading figure of the scientific revolution of the 17th century. Born into a yeoman family, Newton grew up with his grandmother after losing his parents. By the time Newton entered Trinity College in 1661, what we now call the science revolution was well in its course. Nonetheless, Newton’s original intention was to receive a law degree. He immersed himself in philosophy before slowly transferring…

Next time you suffer from a bug bite or a sunburn, relief can be found in your kitchen cabinet at a fraction of the cost of an over the counter remedy. Before you spend money on over the counter treatments, consider what you have in your kitchen cabinet. Baking Soda is very versatile in its uses and can be found in every cabinet to relieve so many common ailments. Once cup of baking soda in a lukewarm bath will sooth a rash or sunburn. One part baking soda and one one part water makes a…

Free Fall Lab Problem Statement: In the following lab report, the following questions will be answered that have to do with the average acceleration due to the gravity on an object in free fall : 1. List the experimental acceleration due to gravity that you measured at each distance 2. Which value do you believe is the most accurate? Why? 3. What factors do you believe contribute to experimental error in this measurement? 4. What could be done to improve the quality of the result? How could…

Proportionality and Newton’s Second Law of Motion Abstract How does increasing the mass of an object affect its acceleration? Is acceleration dependent of the mass of an object? How do they relate? Defining and testing Newton’s second law of motion familiarizes us with this relationship. In this 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…

The mass spring system has two properties, Mass and Stiffness. 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,…

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…

ISE SUMMER PROJECT 2015 Probability, randomness, and chance should be central in any STEM pedagogical model. The concepts of randomness and chance play a very significant role in the essence of all sciences, and especially in the empirical sciences. Randomness is a critical component of biological modeling at many levels in a wide range of systems. The fundamental axioms of the quantum paradigm in physics are, by definition, essentially stochastic. Economics uses the randomness in human thought…

The lab that was conducted in class throughout this whole week was basically to find one suitable objective and that was to determine the friction of four surfaces. It consisted of multiple trials of pulling on a block that was measured at .118 kg, for each specific trial that was conducted. For the block, weights were added on top to determine the friction and how it was affected towards the tension and feel of multiple surfaces that the lab was primarily trying to accomplish. The multiple…
