PHY 305/601 Classical Mechanics Assignment No. 1 1. Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has

Investigating Newton’s 2nd Law of Motion using an Air-track Introduction: My experiment is investigating the Newton’s 2nd law of motion by using an Air-track. The air-track can make the trolley frictionless by testing the velocity with different weights and shows that F=ma. Research question: How much acceleration does the frictionless trolley has? Aim: Use the air track to measure the acceleration of the no friction trolley by hanging with different mass of weights. Apparatus: *

The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis

Debate Opening Statement Can we change our impact on the rate of global warming? There are all these campaigns for us to combat global warming and reduce our emissions‚ we have all the science to maybe not stop it but effectively reduce it to stable conditions. It is evident that the temperatures and sea levels are rising and this proves global warming is out there; but it still doesn’t make a difference we still do nothing because Global warming is irreversible; we are so deep

De’Untre’ Griggs Mr. Hooks 30 September 2014 Physics/4 The Physics Of Dance Essay Physics and dance represent remarkably complementary approaches to human body movement. Those involved with dance and science can easily find the many aspects of science incorporated into the beauty of dance. With its graceful moves‚ jumps‚ turns‚ and kicks‚ dance is a representation of physics at its best and most elegant. Two dance moves in particular come to mind when I think of physics and its effects on dance. They are the grand jeté & projectile motion

play and watch soccer games all of the time and yet few people actually realize the physics that are involved in almost everything that they see or do. While there are multiple ways that physics is used in a soccer game‚ this paper explores three parts and the physics that are involved in each one. The three parts that are going to be discussed are passing‚ heading‚ and throw-ins. These three can explain how physics can work from a soccer ball coming or going in each and every direction. Also‚ every

Short Story: Half A Day Author: Naguib Mahfouz Summary: As the story opens‚ the narrator is a young boy walking to his first day of school. The boy is delighted with the new clothes he is wearing for the occasion‚ but is apprehensive about going to school.
