Electric field
a region in space where a charged object experiences a force
Coulomb's Law
the force between two charges is directly proportional to the product of the charges and inversely proportional to the distance between the charges squared
Potential difference
the work done per unit positive charge
Current
the rate of flow of charge
Ohm's Law
Current through a conductor is directly proportional to the potential difference across the conductor at constant temperature
Resistance
a material's opposition to the flow of electric current
Vector
a physical quantity that has both magnitude and direction
Scalar
a physical quantity that has magnitude only
Resultant vector
the single vector which has the same effect as the original vectors acting together
Distance
the length of path travelled
Displacement
a change in position
Speed
the rate of change of distance
Velocity
the rate of change of displacement
Acceleration
the rate of change of velocity
