- 9coulombs lawinverse square low
- 10multiple chargesnet electric force is equal to the sum of the individual forces
- 11Ecreated by source charges
- 12when illustrating electric field linespoint in direction that positive point charge would move
- 13electric field linespoint away from positive source charges
- 14electric forcetakes two charges and electric field only takes one
- 15electric field EE=kQ/r^2
- 16Electric force due to the fieldF= qE
- 17uniform electric fieldcan use big five
can use w=fdcos theta
electrostatic force and acceleration will be uniform - 18electric dipolepair of equal but opposite charges
- 19eletric field vectoris tangent to the field lines at that point
- 20conductorse
- 21conduction electronsvalence electrons of conductors
- 22electric fieldsany net charge on conductors move to the surface and inside is E = 0
- 23insulatorelectrons not free to roam
- 24nelectrons aren't free to move but the atoms can become polarized where there is negative charge attracted to the external positive charge
- 25spotential energy is positive and work done by gravity is negative
- 26something falls from heightwork done by gravity positive and potential energy negative
- 27increase in potential energyif going against forces of nature
- 28electric potentialpih = kQ/r
- 29electric potenitalis uniform...does not change around a charge
- 30volt VJ/C
units of electric potential - 31change in electrical potential energydelatpe=qV
- 32electric forceconserved
- 33charge experiencesno change in potential energy when initial and final positions are at the same potential
- 34voltagechange in electrical potential energy
- 35positive chargesgo towards lower potential
- 36negative chargeshigher potential
- 37work done by electric field-change in potential energy electitrc
- 38change in kinetic energy =- change in potential energy
- 39electron voltEv = 1.6 x 10^-19
- 40electrical potential can be superimposed as wellso add up the potentials to get total
