Physics Preliminary 8.2 The World Communicates 1. The wave model can be used to explain how current technologies transfer information 1. Describe the energy transformations required in one of the following: – Mobile telephone – Fax/modem – Radio and television A. An energy transformation is a change in the type of energy‚ for example a change from sound energy to electromagnetic waves. Relating this to the mobile telephone‚ it undergoes basic energy transformations of‚ sound wave

because two objects of different masses do fall at the same rate. “Galileo’s measurements indicated that each body increased speed at the same rate‚ no matter its weight. This book is consisted of a lot of theoretical physics‚ which pretty much means is a lot of theories about physics whether it is right or wrong. Stephen Hawking gives a miniscule overview about how the current information was developed. From the universe‚ elementary particles‚ black holes‚ and the beginnings of the universe also what

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

Regents Physics Constant Velocity/ Acceleration Lab 10-3-13 Problem: Graphical Analysis of Constant Velocity and Accelerated Motion. Theory: Gravitational acceleration is constant on Earth g=9.8m/s2 Therefore‚ when the golf ball is dropped‚ the acceleration will be equal to gravitational acceleration agb=9.8m/s2 Given there is no air resistance‚ this means that when the golf ball is dropped from a given distance‚ according to the formulas‚ the golf ball will accelerate

Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

Physics notes Force is an agent which produces or tends to produce motion in an object‚ stops or tends to stop ‚ motion of an object Newton’s 1st law of motion: If an object is at rest‚ will remain at rest until or unless an external force act on it. If an object is in motion ‚ it continues its motion until or unless an external force act on it Newton’s 1st law of motion is also called first law of inertia. Inertia: The tendency of an object to resist any change in its state of motion
