→About Balanced Forces
: When [[force]]s on an [[object]] are '''unbalanced''' it will [[accelerate]] (change speed or direction).
: '''Unbalanced forces''' are related to [[Newton's First Law]] of [[motion]]:
:: An [[object]] in motion will tend to stay in motion in a straight line and an [[object]] at [[rest]] will tend to stay at [[rest]] unless an [[Unbalanced Forces|unbalanced force]] acts upon it.
: If the [[Resultant Force|resultant force]] on an [[object]] is not zero, then the [[force]]s are '''unbalanced'''.
