After running a plastic comb through your
hair, you will find that the comb attracts
bits of paper.
The attractive force is often strong enough to suspend
the paper from comb, defying the gravitational pull.

The ancients knew that if you rub a piece of amber (tree resin)
with a cloth, the amber attracts small pieces of leaves or dust.

Introduction
When a wave strikes the boundaries of its medium,
all or part of the wave is reflected.

Wave Superposition
What happen when a wave pulse or a
sinusoidal wave arrives at the end of the
string?
All or part of the wave is reflected.
e.g. When you yell at a building wall some
distance away, the sound wave is reflected from
the rigid surf

Many common forces are referred to as contact forces.
In contrast, both gravitational and electrical force act over a
distance.
