AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

UNSOLVED MYSTERIES Unsolved Mysteries - Beyond the standard model The Standard Model is nowhere near perfect. It may explain the six quarks‚ leptons‚ and four forces‚ but it is not complete. There are still questions about antimatter‚ dark matter‚ and the inability for the Standard Model to predict particle mass. There is no guarantee that quarks and leptons are actually fundamental. Lastly‚ scientists still don’t understand gravity’s role. Unsolved Mysteries - The standard model as a theory

Physics ABC Book By- Alexis Vellis 2nd period 10/14/12 Atom The basic building blocks of all matter. Atoms are microscopic‚ meaning you cannot see them without a microscope. Black Hole A Black hole is a place in space where the gravity is so strong that nothing can escape it pull. Cyclotron A type of particle accelerator that was created first in the 1930’s. It was made of two Dshaped cavities in a constant magnetic field. Dark Matter A form of matter that is not like ordinary

Global Fiber Optic Sensor Market 2015-2019 rd On 3 Jan 2014 About Spectrum Analyzers A fiber optic sensor is a device that employs optical fiber technology to transmit signals to amplifiers for processing. Qualities such as distributed sensing‚ the ability to withstand high voltage‚ and critical environment conditions help end-users improve the quality of operations and save costs. These benefits have increased the adoption of fiber optic sensors across industries such as Oil and Gas (for drilling

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration

Soccer Physics In this paper‚ I will explain the physics concepts of air pressure‚conservation of energy‚ gravity‚Inertia‚ and impulse momentum as they relate to the sport of soccer. I will also explain how knowing these laws can benefit how you play. The first physics concept I will talk about is air pressure. When you kick a soccer ball more energy transfers to a highly pressurized ball‚ as for a non inflated ball‚ the motion of the kick goes into the ball instead of moving the ball

Although some physical issues appear to be difficult to understand‚ explain James Kakalios achieved from conduction and convection to modern physics. It is much easier to learn when it comes to something you love‚ that’s why the lessons presented in the book seemed understandable. One of the first issues of the second half of the work are phase transitions. Reading the title of the section I figured it would be a very complicated and it would take me a long time to know the subject. I realized‚ the
