the two elements of an electromagnetic force | the electric field and the magnetic field |
electrical charge | is a basic property of the particles in matter |
How many particles are in an electronic charge? | three |
The 3 charges in an elctronic charge are | protons, electrons, neutrons |
a proton has a ____ charge | positive |
an electron has a ____ charge | negative |
A neutron has _____ charge | no or neutral |
The protons , electrons, and neutrons | form various combinations to make up all matter |
When the charges on two particles are the same | a repelling force exists between them |
When two particles have opposite charges | an attractive force exists between them |
When the charges on two particles are the same | they go away from each other |
When two particles have opposite charges | they go towards each other |
The strength of the force | depends on how far apart the charges are |
There is a reciprocal relationship betwen force and distance. | In other words, as the distance increases,the force decreases |
