... charges only when they are moving, and rather than attracting or repelling them, they push them sideways. The magnetic force on a moving charge is always at right angles to the motion of the charge. Since atoms contain moving electrons (charges), we expect them also to exert and feel magnetic forces ...

AP Electric Potential
... electric field. Explain this. A proton loses potential energy when moving in the direction of the electric field, but picks up an equal amount of kinetic energy. Work done by a field is positive when energy is given to an object from the field (object is lowered in a gravitational field or moved in ...

... bottom) becomes so strong that it causes the electrons on the earth’s surface to be pushed down further into the curst (repulsion). This causes the earth’s surface under/near the cloud to become positively charged. So now the bottom of the cloud has a negative charge and the surface of the earth has ...

Lecture 7 - Electric Field
... We will learn about the electric potential in a few classes. For now, consider the following questions: 1. If we stick one positive charge in one corner and a negative charge in the opposite corner, in which direction will the arrows point along the diagonal, and where will the magnitude of the elec ...

... The SI unit of charge is the coulomb (C). The amount of charge transferred when objects like glass or silk are rubbed together is in the order of microcoulombs ( C). 1 C = 6.25 x 1018 electrons or protons and I C = 10-6 C.The charge carried by the electron is represented by the symbol -e, and the ...
