Quantum mechanics (QM – also known as quantum physics, or quantum theory) is a branch of physics which deals with physical phenomena at nanoscopic scales, where the action is on the order of the Planck constant. It departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. It is the non-relativistic limit

The segway What has changed witht the invention of the segway? Steve Jobs said it would be bigger than the PC. Today, it used everyday with police departments, security companies, and golf courses. But the segway didnt revolutionize these departments. The Segway PT is a two-wheeled, self-balancing, battery-powered electric vehicle. It was marketed as a balance-sensitive machine that could transport a human at about 13 m.p.h. and last for a day on only 5 cents-worth of electricity. This brought

Acceleration of a Cart Purpose: The purpose of this lab is to find the relationship between acceleration, force and mass using a cart system. Equipment: • Motion detector • Pasco GLX • Cart • String • Pulley • Hanging Weights & Metal Cubes • Ramp • Ruler Procedure: Experiment 1: 1. Weigh and record the mass of the cart (this will be kept constant for all trials) then the mass of the cart with all the hanging weights on top

1A. Ask a Question- Good questions come from careful observations. You make observations by using your senses to gather information. Sometimes you may use instruments, such as microscopes and telescopes, to extend the range of your senses. Questions beginning with what, why, how, and when are very important in focusing an investigation, and they often lead to a hypothesis. 1B. Form a Hypothesis- A hypothesis is a clear statement of what you expect the answer to your question to be. Your hypothesis

Composition and Resolution by Vector Methods OBJECT: To study the composition and resolution of vector quantities. METHOD: Concurrent forces acting on a body are used as examples of vector quantities. These forces are represented by vectors. The resultant and equilibrant of several sets of such known forces are determined by both graphical and analytical methods. These results are tested on a force table as a check on the first condition for the equilibrium of a rigid body. THEORY: Measurable

Circular Motion and Gravitation Centripetal Acceleration and Centripetal Force 1. What is the centripetal acceleration of a point on the perimeter of a bicycle wheel of diameter 70. cm when a bike is moving at 8.0 m/s? 2. A pilot is upside down at the top of an inverted loop of radius 3.20 x 103 m. At the top of the loop his normal force is only one-half his normal weight. How fast is he going? 3. The maximum force a pilot can stand is about seven times his weight. (This is his

* Derive the expression shown on the site for a and s. (What the site calls s, is actually displacement or ∆x). Please note that s or ∆x is simply the distance from the starting point of the wagon to the light barrier. Remember, the wagon begins starts from rest. * Vary the values of M, m and , so that you have 2 different combinations. Make sure that is zero (frictionless case) for the first combination and non-zero(case with friction) for the other. For example, for you first run, M

Natriumhydrogencarbonats omdannelse Af Nynne Viktoria Sass Larsen, 1.d Formål Formålet med opgaven er at finde hvilket af reaktionsskemaerne der er den rigtige kemiske reaktion ud fra en teoretisk og en praktisk del. Vi skal hermed bestemme hvilken omdannelse der finder sted, når stoffet NaHCO3 bliver ophedet. Teori NaHCO3 bedre kendt som natron, bruges som et hævemiddel i bl.a. kager. Stoffet består af et salt, altså en ionforbindelse, og kulsyre. Årsagen til at dette bruges som hævemiddel
