Refractive index "n" of glass
is
how much light slows down
when it enters glass
n = speed of light in vacuum (or air)

A see-saw will balance if the moments on each side of the pivot are equal. This is why you might have to adjust your position on a see-saw if you are a different weight from the person on the other end.

If a nut is difficult to undo with a short spanner, a longer spanner will help. This is because there will be a bigger moment on the nut, when the same force is applied further from the pivot.

Using the same principle you can increase the moment applied by a lever or a crowbar, and this can help you move heavy objects more easily.
