Current is defined as the flow of electrons. This flow is caused by the electrons within the wire being pulled by electric field. As the electrons travel through the wire they collide with the atoms that...

The SUVAT equations for motion are as follows:v = u + at s = ((u + v)/2)t s = ut + (1/2)(a)(t^2) s = vt - (1/2)(a)(t^2) v^2 = u^2 + 2asThe last 3 equations can be derived from the first two, but will also...

We know that the displacement, x, is described by the equation x = Acos(ωt + Φ), where A is the amplitude of oscillation, ω is the angular frequency and Φ is the phase shift. The velocity, v, is the time ...
