21. Newton's Laws: Specificity For Objects With Variable Mass CLASSICAL MECHANICS Specificity of Newton's laws for objects with variable mass http://classicalmechanics.net/

CLASSICAL MECHANICS Specificity of Newton's laws for objects with variable mass Classical mechanics is the physics of forces, acting upon bodies. It is often referred to as "Newtonian mechanics" after Newton and his laws of motion. Classical mechanics produces very accurate results within the domain of everyday experience. It is superseded by relativistic mechanics for systems moving at large velocities near the speed of light, quantum mechanics for systems at small distance scales, and relativistic quantum field theory for systems with both properties. Nevertheless, classical mechanics is still very useful, because (i) it is much simpler and easier to apply than these other theories, and (ii) it has a very large range of approximate validity. Classical mechanics can be used to describe the motion of human-sized objects (such as tops and baseballs), many astronomical objects (such as planets and galaxies), and even certain microscopic objects (such as organic molecules.)

IMPORTANT CHANGE The incessant spamming we got by having our email address published in the "Are there any questions?" mailto links on the pages in this website forced us to place an impediment to the automated email address gathering programs out there. If you click on a question mail link your mail handler should open up with a To: address in the form xxxxxAxxxx.com. You will need to replace the A with the @ symbol before you can send the question. If you try to send the question with the A in the address it is likely that your mail handler will complain to remind you that the address is illegal. Click on the "Are there any questions?" link farther down this page for an example. Hello. My name is J. D. Jones . To find out more about me and my background just click on my name which should appear underlined and in a distinct color. That underlined and colored name is an example of a "link". I will use links throughout this on line textbook to let you jump to new topics.

Just pause your cursor over any image to see a description. Those of us who write online material including Java applets, and those of you who need to run those applets are caught in the crossfire of the Java war. Microsoft tried to take over the Java virtual machine business a few years ago and failed. Sun Microsystems, the original Java company, won that battle and Microsoft is giving up, abandoning their Java technology and their support for Java. All new computers will now be shipped with the Sun Java runtime environment(JRE). That means that when websites are updated, the authors must make a choice about whether or not to move up to the modern Java language, not constrained by the limitations of the Microsoft virtual machine. At M. Casco we have decided to move on, since the move will be have to be made sooner or later. Consequently if you have a computer shipped before 2004, you will probably need to

Classical Mechanics John Baez Here are some course notes and homework problems for a mathematics graduate course on classical mechanics. There are two versions of the course: Classical mechanics: the Lagrangian approach Classical mechanics: the Hamiltonian approach The second course reviews a lot of basic differential geometry. But, if you'd like to study these courses on your own and don't feel comfortable with manifolds, vector fields, differential forms and vector bundles, you might try the following texts, in rough order of increasing sophistication: Gregory L. Naber, Topology, Geometry and Gauge Fields: Foundations , Springer, Berlin, 1997. Chris Isham, Modern Differential Geometry for Physicists , World Scientific Press, Singapore, 1999. John C. Baez and Javier P. Muniain, Gauge Fields, Knots and Gravity , World Scientific Press, Singapore, 1994. (My favorite, for some reason. For this class you just need chapters I.2-I.4 and II.1-II.2.) Harley Flanders, Differential Forms with Applications to the Physical Sciences , Dover, New York, 1989. (Everyone has to learn differential forms eventually, and this is a pretty good place to do it. Plus, Dover books are cheap!)

Thursday October 28, 2010 One of the hallmarks of genius is being able to look at two things which are unrelated and seeing how they can work together. Consider coffee grounds, which often come packaged in bags as a hard little brick. However, when you open the grounds and air is allowed back in, it's no longer hard. This curious behavior is known as jamming transition. Next, consider the human hand. It's a tricky thing to replicate, as robot designers can well attest. Designs for gripping are not very dexterous or versatile. The problem is that objects come in lots of different shapes and it's hard to design one single gripper that can handle a wide assortment of shapes. The universal gripper robotic hand.

33. Gravity Provides definitions of gravity. http://www.angelfire.com/geek/alphabeta/

Home Zero Gravity Specific Gravity What is Gravity? Gravity is a force of attraction only between bodies that have mass. The word 'gravity' comes from the Latin word "gravitas", meaning 'weight'. The force of gravity that one body exerts on another can be expressed as: F = Force of gravity experienced by bodies. m = mass of body. G = Gravitational constant , 6.6726 * 10 m kg s . m = mass of second body. r = radius of body. From this an important equation for finding the force of gravity on an object e.g. planet. F = m * a. (2) Divide both sides by m and you will get: At a 90 degree angle: a = g (5) So the new formula is: Knowing the gravitational constant, the mass of the Earth, and your distance from the centre of the Earth, you can work out the gravity of Earth.

Now you're barreling down the track at 60 miles per hour, taking hairpin turns and completing death-defying loops. Your heart is in your throat and your stomach is somewhere near your shoes. The only thing separating you from total disaster is a safety harness...but are you really in danger? The designers of the roller coaster carefully crafted this thrilling ride to be just that, but you're actually in less danger than you think. You face a greater threat of injury playing sports or riding a bike than you do on a park ride. Amusement park rides use physics laws to simulate danger, while the rides themselves are typically very safe.

About Presses Classical mechanics Classical mechanics is the physics of forces , acting upon bodies. It is often referred to as "Newtonian mechanics" after Newton and his laws of motion . Classical mechanics is subdivided into statics (which deals with objects in equilibrium) and dynamics (which deals with objects in motion). Classical mechanics produces very accurate results within the domain of everyday experience. It is superseded by relativistic mechanics for systems moving at large velocities near the speed of light, quantum mechanics for systems at small distance scales, and relativistic quantum field theory for systems with both properties.

Classical mechanics can be used to describe the motion of human-sized objects (such as tops and baseballs), many astronomical objects (such as planets and galaxies), and even certain microscopic objects (such as organic molecules.) Although classical mechanics is roughly compatible with other "classical" theories such as classical electrodynamics and thermodynamics, there are inconsistencies that were discovered in the late 19th century that can only be resolved by more modern physics. In particular, classical nonrelativistic electrodynamics predicts that the speed of light is a constant relative to an aether medium, a prediction that is difficult to reconcile with classical mechanics and which led to the development of special relativity. When combined with classical thermodynamics, classical mechanics leads to the Gibbs paradox in which entropy is not a well-defined quantity and to the ultraviolet catastrophe in which a blackbody is predicted to emit infinite amounts of energy. The effort at resolving these problems led to the development of quantum mechanics.
