: When a [[force]] acts on an [[object]] with a [[pivot]] it becomes a turning force called a [[moment]].
: A '''moment''' can be calculated by multiplying a [[force]] by the [[distance]] from a [[pivot]].
: '''Moment'''s can be used to make [[Force Multiplier]]s using a [[pivot]] and [[lever]].
: The longer the lever, the larger the [[moment]] that can be produced.
