1. Properties of light Reflection The speed of light is measured through the equation: v = λ f. However‚ it turns out that when light is reflected off a surface its speed stays the same. This was first proven by Sir Isaac Newton. Under the assumption of perfectly elastic collision‚ the laws of reflection follow from the laws of motion. To demonstrate‚ consider a particle traveling towards a flat frictionless surface whose horizontal and vertical velocity components are: VX and VY. When the particle

Accident Investigation Physics‚ Module 2 - Honors Extension Introduction: After a motor vehicle accident occurs‚ it will usually be investigated. Sometimes it will be reconstructed. The people that perform these duties are police and independent investigators. Accident investigation: The police will investigate an accident focused on any criminal actions which took place during the accident. For example: speeding‚ alcohol use‚ drug use‚ etc would be considered a criminal action

spans all the way to the many and varied coasters of today. It is known that by 1817 two coasters were built in france called the les montagnes. The first roller coaster was made out of wood in january 20‚ 1885‚ it was also called lamarcus adna. They were designed so that the axle of each car fit into an open area carved in the side of the track and served as an equivalent to the modern day upstop wheel. The first looping coaster was located in frascati gardens in paris france. Why was the roller

Module 2 Honors Extension: The Physics in Swimming Physics is defined as the branch of science concerning the study of matter and energy and the interactions between the two. Physics tries to explain the nature of the world around us‚ how things happen and why. Swimming displays some physical properties‚ such as buoyancy‚ drag resistance and propulsion. We swimmers are at a constant battle to stay afloat‚ while fighting through the water and propelling ourselves forward‚ and we do so using technique

Physics takes place in every aspect of our lives. From the time we get out of bed until the time we get back into our bed. Physics influences are far beyond the classroom. If you’ve ever wondered what makes lightning‚ why baseball pitchers throw so fast‚ how track stars can run so fast‚ how Lebron James can jump so high. Why some people are stronger than others‚ how that tiny computer can do complicated problems‚ or how long it takes light from the sun to reach us. All of these questions are studied

Physics in Sports Introduction Billiards‚ Pool or 8 Ball are the names given to this game. For many of us 8 Ball is a game that we play at friends’ place or at pool houses‚ pubs and a good many other places. But when you are playing 8 Ball you would never really think about physics would you? But it is there‚ and it is in play everytime the cue hits the ball to make it curve‚ everytime you jump the ball over another or bounce it around the cushioned sides to get the white ball
