FYS-Presentation/Midterm test October 14‚2014 Topic: Abuse of power in the police force – There has to be an invisible sun that gives us hope when the whole day is done. Introduction: Nowadays a lot of killings have taken place in various parts of the world e.g. U.S.A‚ U.K and many more. There have been a lot of misconduct with the police force. The reason why I picked this research‚ is due to the abuse of power in the police force. A lot of young people have died‚ because of petty incidences or racism e

transcontinental plane flight‚ your coffee cup sits motionless on your tray. Are there forces acting on the cup? If so‚ how do they differ from the forces that would be acting on the cup if it sat on your kitchen table at home? Determine the Concept Yes‚ there are forces acting on it. They are the normal force of the table and the gravitational pull of Earth (weight). Because the cup is not accelerating relative to the ground‚ the forces are the same as those that would act on it if it was sitting on your table

001 CP1 Lab Report - Projectile Motion October 12‚ 2009 The purpose of Lab Assignment 1 was to analyze projectile motion. In doing so‚ we determined the initial velocity of the ball shot horizontally from the spring loaded projectile launcher. Also‚ we verified the angle at which the projection of the ball would produce a maximum range. Lastly‚ we predicted the range that a ball would travel at a certain angle‚ theta. Projectile motion is the motion of objects that are initially launched

Exploration Guide: Uniform Circular Motion Go to www.explorelearning.com and login. Please type or write your answers on a separate sheet of paper‚ not squished in the spaces on these pages. When relevant‚ data collected should be presented in a table. Objective: To explore the acceleration and force of an object that travels a circular path at constant speed. Motion of this kind is called uniform circular motion. Part 1: Centripetal Acceleration 1. The Gizmotm shows both a top view and a

Projectile Motion By Kaneisha Winch Aim: To investigate whether there is a relationship between the horizontal velocity and vertical velocity by using a 7.5 cm baseball in projectile motion. Hypothesis: There is no relationship between the horizontal and vertical velocity. No matter how fast the horizontal velocity‚ the vertical velocity will remain the same. This has no relation to the size or mass of the ball. Materials: • a baseball with a diameter of approx. 7.5 cm • a tape measurer • a surface

BCA- I Physics Assignment 1 Unit I Laws of Motion 1. A man of mass 70kg stands on a weighing machine in a lift which is moving (a) upwards with a uniform speed of 10m/s. (a) downwards with a uniform acceleration of 5m/s2 . (a) upwards with a uniform acceleration of 5m/s2. What would be the readings in each case? (d)what would be the reading if lift mechanism failed and it hurtled down freely under gravity? 2. A shell of mass 0.2kg is fired by

CURTIN UNIVERSITY OF TECHNOLOGY DEPARTMENT OF APPLIED PHYSICS Physical Measurement 201 DRIVEN HARMONIC OSCILLATOR Abstract The purpose of this experiment is to investigate the various aspects of harmonic motion using a Driven Harmonic Motion Analyser (DHMA). The aspects that are investigated in this experiment is the spring constant k of two springs‚ the resonant frequency‚ the damping factor‚ and the relationship between phase and resonant frequency. The value of k of the first

Case Study: YouTube‚ the Internet‚ and the Future of Movies Question 1 The movie industry was face with competitive forces that made the industry unattractive. The threat of substitutes was extremely high. This was because the increased levels of high speed Internet made downloading easier and faster‚ which made pirating movies easier. This increased the threat of substitutes because consumers were no longer buying movies‚ the consumers started to download movies and television shows free of

“The solution of the difficulty is plain: motion is in the movable. It is the fulfilment of this potentiality by the action of that which has the power of causing motion; and the actuality of that which has the power of causing motion is not other than the actuality of the movable; for it must be the fulfilment of both. A thing is capable of causing motion because it can do this‚ it is a mover because it actually does it. But it is on the movable that it is capable of acting. Hence there is a single
