... A motor performance curve is a picture showing the relationship between inputs and outputs. Let's choose motor speed in revolutions per minute (RPM) as a reference point and look at torque. Torque is a measure of the force a motor can develope to turn something. Begin in the lower left corner of the ...

... • How does one charge know that another charge is there? (“Action at a distance”). • A charge actually changes the space around it; a force field is caused. • Other charges interact with this “Electric Field”. • The Electric Field due to a “source” charge (qs): E = k qs /r2 ř (a vector) The direct ...

Many early books on electrical engineering are full of talk about the "density of lines.” Field lines and equipotentials are a useful way to think about what electric force will be exerted on a charged particle that is in the vicinity of other charges. Closely spaced field lines are associated with ...

... Consider a sphere of radius R and charge q. In the region outside the sphere it will generate an electric field that is that of a point charge q, located at the center of the sphere. The electrostatic potential in this region is thus also that of a point charge, and we thus conclude that the electro ...

This is proven by noting all flux lines originate or terminate at a charge, or go to infinity. Therefore a flux line originating from a charge outside the spherical shell and whi ...

Speed of gravity

In classical theories of gravitation, the speed of gravity is the speed at which changes in a gravitational field propagate. This is the speed at which a change in the distribution of energy and momentum of matter results in subsequent alteration, at a distance, of the gravitational field which it produces. In a more physically correct sense, the ""speed of gravity"" refers to the speed of a gravitational wave, which in turn is the same speed as the speed of light (c).
