Umm... i think its because the longer the string the further distance the pendulum is able to swing, to the time taken will be longer than a  pendulum with a shorter lengthed string. 

The length of the string determines how much the pendulum is able to swing, so a short lengthed pendulum would take a short duration of time for one oscillation because it cant 'move' / 'swing' as much.

Am i making sense? Im not good at explaining things but yh. Hope  i helped a tiny bit atleast. trying drawing a diagram of a pendulum with a long and short string, may be that would help my explanation.

Ooh I'm also going to do an ISA based on pendulums. Well, the longer the pendulum, the longer the time period and the shorter the pendulum, the shorter the time period.
