Electric Field & Potential A positive test charge has electric potential energy due to its position in an electric field The amount of electric potential energy depends on: The magnitude of cha...
Electric Field due to a Point Charge The electric field strength describes how strong or weak an electric field is at that point A point charge produces a radial field A charge sphere also acts lik...
Electric Force between Two Charges All charged particles produce an electric field around them This field exerts a force on any other charged particle within range The electrostatic force be...
Electric Field Strength The electric field strength at a point is defined as: The force per unit charge acting on a positive test charge at that point The electric field strength can be calculated ...
Defining an Electric Field An electric field is defined as a region of space in which a charged particle experiences a force Hence, electric fields are a type of force field The charged particle co...
Centripetal Force Centripetal force can be calculated using any of the following equations: Centripetal force is always perpendicular to the direction of travel Where: F = centripetal force...
Maintaining Circular Motion An object moving in a circle is not in equilibrium, it is constantly changing direction Therefore, in order to produce circular motion, an object requires a resultant fo...
Deriving Equations for Centripetal Acceleration An object moving in uniform circular motion travels with a constant angular velocity and angular speed However, its direction is always changing Ther...
Angular Velocity The angular velocity ω of a body in circular motion is defined as: The rate of change of angular displacement In other words, angular velocity is the angle swept out by an object i...
