Equation is--- Current= charge moving past a point/ time or I=Q/T I in Amps, Q in Coulombs, t in seconds
Potensial difference is a measure of how much energy is transferred between two points in a ciruit. the equation is V=E/Q (e is enegry, v is Pd and q is the charge V=IR (V= PD, I is current, R is resistance

Wave charcterisicts
Transverse
They are able to travel through a meduim and a vaccum (enpty space0. The oscilations are perpendicular to the direction of energy transfer !--------------------
-
Longitudinal
they can only travel through a medium and cant travel through a vacum/. The oscilations are parellel to the directon of energy transfer. ------__

Centre of mass
-
example= the centre of mass in a doughnut is the centre of the hole. or the centre of mass is were the x and y axis intercept.
-
Resultant forces
the resultuntant force is the force that is the strongested and the direction of it as its a vector quantity.
