Why do capacitors dis/charge suddenly and then slow down?

Capacitors are made up of two plates (& so the symbol) which you can imagine as 'boxes' of opposite polarity and are seperated with insulation. As capacitors charge, the negative box keeps filling with e...

A ball is kicked from a tower (50m) at a speed of 20m/s. How far away does the ball hit the ground?

time is equal to time in free fall i.e. 50m=0.5 g t^2 -> t=root(50m*2/g)=1.019s horizontal distance is then t v= 1.019s 20m/s=20.38m

What is damping in Simple Harmonic Motion?

An oscillation is damped if resistive forces are present e.g. air resistance or friction. The amplitude of the system will decrease over time, as opposed to a free oscillation which is undamped (no resistive...
