Goal The goal of this experiment is to verify Newton’s 2nd Law of Motion. Introduction Newton’s 2nd Law states that when an external net force acts on an object, the acceleration of the object is proportional to the net force, and it also occurs in the same direction. The acceleration is also inversely proportional to the net force. Thus, the net force, which is the sum of all the forces acting on an object, is equal to the mass of the object multiplied by its acceleration. In this experiment,…

The two graphs of the distance vs. time graph along with the velocity vs. time graph, accurately supports the hypothesis formed at the beginning of this experiment. From the interpretation of the first graph, the chart vaguely shows the changing velocity (acceleration) as well as positive velocity of the objects motion (as seen from the slight curve upwards). However, from another perspective, it might seem as if the diagram is showing a constant, positive velocity as the line is linear with no…

Jack Shumski Professor Verdecia Fire Technology 102 20 November 2017 Physical Principle of a Catapult to The Fire Service A catapult does many different things that relate to different physical principles. The big physical principle of the catapult is it uses Newton's first, second and third law. In fact, also all three of Newton's law can relate a lot to the fire service and how it operates. This essay will relate the physical principle of the catapult, to Newton's laws and how it relates to…

Experiment 37: Friction Anne Smolinski as910513@ohio.edu Wednesday 11:50-1:40 TA: Sanjoy Sarkar November 11, 2017 Experiment 37: Technical Report ABSTRACT In experiment 37, the friction force is being explained and tested by using a block that is being pulled across a wooden base. Out of the four different types of friction, two will be tested during this experiment: (i) static and (ii) kinetic. Static friction can be defined as the force that resists motion of an object to a surface so…

1.1. Mechanical properties of CP/CNF and CP/CNF/ZIF-67 1.1.1. Stress–strain curves The stress–strain curves and the effects of CNF dosage on the tensile strength, elastic modulus, and elongation at break of CP/CNF and CP/CNF/ZIF-67 are shown in Fig. 3 and Tables S1–S4. As shown in Fig. 3(A) and Table S1, the tensile strength, elastic modulus, and elongation at break of neat CP is 7.37 MPa, 996 MPa, and 3.07%, respectively. After coating and crosslinking with CNFs, the mechanical properties of…

Quasiclassical Elienberger equations [129] for the green functions g(k , r, and order parameter , is a powerful tool to deal with inhomogeneous superconductors [130]. These functions depend on the so called, ‘Matsubara frequency’, , coordinate r, and wave vector k on the fermi surface. The dependence of green functions and order parameters on the wave vector k, makes them sensitive to the shape of fermi surface. This makes solution of Elienberger equations complicated in the system of complex…

Sir Isaac Newton was one of the most influential scientists of all time. His ideas became the basic principles for physics according to http://www.livescience.com/46558-laws-of-motion.html. Newton is known for his work in gravity and the motion of planets. Isaac Newton based his discoveries off of Descartes and changed the modern era of scientific thinking. In mathematics, Newton created integral and differential calculus, and in optics, he created the first telescope. His most influential and…

The speed of light is the ultimate speed limit in the universe. Which travels at 3.0 x 108 m/s in a vacuum and always moves in a straight line. When light travels to a new medium its speed and direction will change, this is called refraction. Materials have different optical density so light rays travel at different velocities. Refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium. Calculated by the velocity of light in vacuum divided by velocity in a…

When people think of Isaac Newton and the contributions he made to science they usually think of his law of gravitation, but there is so much more. He came up with the three laws of motion, theory of light, and the universal law of gravitation. Newton transformed the history of science. In the first three years when Newton was at Cambridge, he, like everybody else, was taught the standard curriculum, but he was more interested in the advanced science. (Isaac Newton, 1) One of his very first…

Daniel Bernoulli, proclaimed to be the greatest out of all the Bernoulli in his family, made the basis for the kinetic theory of gases, applied the idea of Boyle’s law, worked on elasticity with Leonhard Euler, the development of the Euler-Bernoulli beam equation, and one of the most important Bernoulli’s Principle which is critical to aerodynamics. At the beginning of Daniel’s life he wasn’t allowed to choose what he wanted to be or be able to pursue the career he wanted, but this shaped the…
