→About Acceleration
: [[Newton's First Law]] indicates that [[acceleration]] occurs due to [[Unbalanced Forces|unbalanced forces]] on an [[object]]:
''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 Force|unbalanced force]] acts upon it.''
===Force and Acceleration===
: [[Newton's Second Law]] indicates that [[acceleration]] of an [[object]] is [[Directly Proportional|directly proportional]] to the [[Resultant Force|resultant force]] on the [[object]] but inversely [[proportional]] to its [[mass]].
