Electric Field - A region in which a force is exerted on a charged object, Electric Field Strength - The force per unit positive charge experienced by a small test charge at that point, N/C - Units of electric field strength, Uniform field - Field lines are parallel and equally spaced., Field Line - A line indicating the direction of force experienced by a positive charge, Strenght of the electric field - Represented by the density of the field lines, Permittivity of free space - the ability of an electric field to pass through a vacuum., Force between 2 charged objects - Directly proportional to product of charges, Radial Field - Field lines spread out from a point charge, Point charge - We can approximate a uniform charged sphere as this, Positive - If the force is repulsive it will have this sign, Negative - If the force is attractive it will have this sign, 8.99 x 10^9 - Value of 1/ 4 x pi x Eo, 8.85 x 10^-12 - Value of Eo, Uniform Electric field strenght formula - Potential difference / plate separation, Radial Electric field strenght formula - K x Q / R^2, Parallel to field lines - A charged onject that is stationary in an electric field will move like this, Parabolic path - A charge particle moving perpendicular to field lines will take this path, General Electric FIeld Strength formula - F / q, Vector - Electric fields are this type of quantity, Scalar - Electric (and gravitational) potential is this type of quantity,
