Force print that page


In physics , a force is any influence that causes a object to undergo a change in speed, a change in direction, or a change in shape. Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity (which includes to begin

Lorentz force print that page


In physics , the Lorentz force is the force on a point charge due to electromagnetic fields . It is given by the following equation in terms of the electric and magnetic fields : [ 1 ] where F is the force (in newtons ) E is the electric field (in volts per metre ) B

Non-contact force print that page

A non-contact force is a force applied to an object by another body that is not in direct contact with it. The most common example of a non-contact force is gravity . A non-contact force is different from a contact force , which is a force applied to a body by another body that is | 2011/8/15 14:57:59

Force field print that page

A force field , sometimes known as an energy shield , force shield , or deflector shield is a concept of a field tighly bounded and of significant magnitude so that objects affected by the particular force relating to the field are unable to pass through the central axis of the field and | 2011/7/27 21:06:33

Magnetic radiation reaction force print that page

In the physics of electromagnetism , one can derive an electric radiation reaction force for an accelerating charged particle caused by the particle emitting electromagnetic radiation . Likewise, a magnetic radiation reaction force can be derived for an accelerating magnetic moment | 2011/7/3 11:53:34

Fictitious force print that page

A fictitious force , also called a pseudo force , [ 1 ] d'Alembert force [ 2 ] [ 3 ] or inertial force , [ 4 ] [ 5 ] is an apparent force that acts on all masses in a non-inertial frame of reference , such as a rotating reference frame . The force F does not arise from any physical | 2011/2/23 5:01:25

Magnetic field print that page


a vector field . [ nb 2 ] The magnetic field is most commonly defined in terms of the Lorentz force it exerts on moving electric charges. The relationship between the magnetic and electric fields, and the currents and charges that create them, is described by the set of Maxwell's equations

Electromotive force print that page


In physics , electromotive force , emf (seldom capitalized), or electromotance (dentoed ε and measured in volts ) refers to voltage generated by a battery or by the magnetic force according to Faraday's Law , which states that a time varying magnetic field will induce an electric current

Electromagnetic field print that page

An electromagnetic field (also EMF or EM field ) is a physical field produced by moving electrically charged objects . It affects the behavior of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic | 2011/8/13 23:21:31

Force carrier print that page

fields . Each field has a complementary description as the set of particles of a particular type. A force between two particles can be described either as the action of a force field generated by one particle on the other, or in terms of the exchange of virtual force carrier particles | 2011/4/28 2:51:52
