The Big 50 Revision Guidelines ‐ M1 OPHS The Big 50 Revision Guidelines for M1 If you can understand all of these you’ll do very well… 1. Understand what is meant by a Model in Mechanics‚ and why all real‐life systems have to be modelled in order to be analysed theoretically 2. Know how everyday objects are modelled as Particle‚ Lamina‚ Rigid Body‚ Rod (Light‚ Uniform‚ Non‐ uniform)‚ String (Light‚ Inextensible)‚ Pulley (Light‚ Smooth)‚ Surface (Rough‚ Smooth)‚ Bead‚ Wire and Peg

Physics C-110 Module 1 Chapter 1 1. What is science? Science is a body of knowledge that is ever changing. It is made up of not only facts but also theories that are made up of well-tested hypotheses. 2. Distinguish among the scientific fact‚ hypothesis‚ law and theory As stated above‚ a theory is made up of well-tested hypotheses‚ which in themselves are well educated guesses yet to be proven. A fact is something that can change over time even though it was agreed upon by knowledgeable

Macarilay Department of Math and Physics College of Science‚ University of Santo Tomas España Street‚ Manila Philippines Abstract Kinematics is the branch of classical mechanics that describes the motion of bodies and systems without consideration of the forces that cause the motion. There are four activities done in this experiment. Graphical analysis of human motion‚ where displacement vs. time and velocity vs. time were

YOUNG’S DOUBLE SLIT EXPERIMENT Interference Patterns This report will be performed by a group of 3 students viz. Harleen Kaur‚ Rutvi Patel and Sandhya‚ determining the wavelength of light from a laser using a double – slit slide. The laser was shone through the double – slit such that it projected interference pattern onto the paper screen. The experiment will be repeated three times varying the distance between the slit and the screen to understand the effective relationships. The expected wavelength

Introduction Isaac newton—English astronomer‚ physicist‚ mathematician‚ and scientist—became interested in science as a boy and even invented several devises while he was still young. He attended Cambridge University and later taught there. In Optics‚ newton published his principles of light and colour‚ and in his mathematical principles of natural philosophy (also known as the principia)‚ he discussed the laws of motion and the theory of gravity. Besides his scientific study‚ he spent much time

In Raymond Carters’ “Popular Mechanics” the way he foreshadows and uses literal response sets the mood of the text. Carver foreshadows the fact that the inside of the house is full of “darkness”. He also uses literal response with the way the unnamed man replied to his wife. That causes the reader to feel the seriousness of the man. This affects the readers experience because it really makes them feel the intensity of the scene. Carvers’ choice of words set a dark mood for the story. The last sentence

Open-ended Investigation (mass and force) Aim: To show the relationship between Mass‚ the force acting on it‚ and acceleration by gathering data through investigations. Hypothesis: As Mass increases‚ Acceleration Decreases. Therefore‚ Acceleration is inversely proportional to mass. Introduction A force is a push or pull acting upon an object‚ as a result of its interaction with another object. In a state of motion‚ an object experiences different forces which influences its movement. There are many

Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body‚ following a curved path‚ has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum.<br><br>Torque is the angular "version" of force. The units for torque are

Through using symbols in the short story “Popular Mechanics” Raymond Carver exemplifies that the lack of communication in a relationship causes estrangement and struggle. Although
