Science Fair 2018- Rock and Roll Bounce Observation What is friction? What is the difference between motion and forces? Are there different types of motions and forces? What is gravity? What is Newtons law? Does friction have to do with motion or force? Does Newton's law apply to everything that is moving? How is movement and forces apply to the world itself? Do natural disasters involve motion and forces? Does energy have to do with motion and forces? How many types of…

Presentism is the view that all, and only, things that exist in the present, the now, exist. To determine whether something is part of the present means that you have to find what exactly determines the present. The common objection for presentism is by the use of the Special Theory of Relativity, or more specifically the relativity of simultaneity. The Special Theory of Relativity is a well confirmed physical theory of the measurement of non-accelerating frames of reference in all inertial…

unable to connect to Houston, and are faced with space debris travelling at a high velocity. Wolf Kohn – a former NASA Engineer – says that this scene is inaccurate as the debris is travelling at a velocity that is too high. According to orbital mechanics, the higher an object’s orbit, the slower its velocity, and the longer the amount of time it takes to complete an orbit. Therefore, objects in the same orbit should have the same relative velocity; unless coming from a higher or a lower…

INTRODUCTION • Energy is a scalar quantity. • It was first hypothesized by Newton to express kinetic and potential energies. • We cannot observe energy directly, but we can measure it using indirect methods and analyze its value. • Energy may be in different forms, such as potential, kinetic, magnetic or electrical. Potential energy of a system is by virtue of its location with respect to gravitational field. If an object has a mass m, located at elevation h, and acceleration due to gravity is g…

Evie McCormack Mr. Acland B Block Physics Lab: Speed of Sound Essential Question Asked: How does the speed of sound differ between metals and gases? Background Information: The speed of sound is gauged by distance over time (distance/time). Certain aspects that can change or affect the speed of sound would include the density of the item through which the sound is traveling. Continuing on with that concept, when sound is…

Research question: To what extent is the maths behind the double pendulum correct and what are its limitations due to chaos theory. Chaos theory is the idea, in simple terms, that certain natural events and occurrences are unpredictable in their behaviour. Examples of this are: weather, turbulent flow in certain liquids and even the double pendulum. These things can be explored and determined mathematically just how unpredictable they are and under what conditions they may become predictable,…

Sir Isaac Newton was born on December 25th, 1642. As Newton grew up he was recognized as a very knowledgeable physicist, mathematician, author and astronomer. He excelled in both math and physics and has been developing theories since his early twenties. Isaac Newton attended a grammar school in Grantham near Lincolnshire, where as during this time Newton became very interested with chemicals. In 1664 Newton at that time was a student, he read up on work containing optics and light. He was…

DESCRIPTION In the paper titled “Non-Markovian coherence and entanglement transfer in a quantum version of Newton’s cradle”, Mu and co-author have presented the quantum analog of the classical Newton’s cradle. An array of couple cavities (coupled with a common Markovian and non-Markovian environment) with nearest neighbor hopping interaction between the cavities, has been selected as the quantum cradle. In the case of quantum cradle with Markovian baths, single exception transfer is used…

The topic of mechanic work is so engaging to me that I lose track of time. Just being under the car or truck and looking at the engine. Just being around cars and learning about how they work has made me lose track of time. I love it. Just being able to hear the engine turn over after me and my dad worked on the car, it amazing. I love the feeling. My Dad, my Grandfather, and I worked on my Step-mom's car because it wouldn’t start. It would start with jump starting it. We had to change the…

research into Farm Equipment Mechanics. I have chosen this because I want my career to be Agriculture related. I do not know yet what I want to pursue as a career. I think that I am capable of having a more efficient career. I would like to pursue a more well paid job than what I am researching about. Even, after researching the career of a Farm Equipment Mechanic, i have not decided whether or not I want to pursue this career. Concerning daily tasks, farm equipment mechanics are required to…
