: [[Newton's First Law]]: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.: [[Newton's Second Law]]:Force = Mass x Acceleration, which means the [[acceleration]] of an [[object]] is [[Directly Proportional|directly proportional]] to the [[Resultant Force|resultant force]] acting upon it.: [[Newton's Third Law]]:For every [[Action Force|action force]] there is a [[Reaction Force|reaction force]] with an equal [[magnitude]] but acting in the opposite direction.: [[Hooke's Law]]:The [[extension]] of an [[elastic]] [[object]] [[Directly Proportional|directly proportional]] to the [[force]] applied to the [[object]].: [[Ohm's Law]]:The [[Electrical Current|current]] through a [[Electrical Resistor|resistor]] at constant [[temperature]] is [[Directly Proportional|directly proportional]] to the [[Potential Difference|potential difference]] across the [[resistor]].: [[Conservation of Energy|The Law of Conservation of Energy]]:Energy cannot be created or destroyed it can only be transferred from one store into another.
