'''Newton's Universe Theory of Gravitation''' is a [[Scientific Theory|scientific theory]] developed by Sir [[Isaac Newton]] that [[explain]]s that the [[planet]]s are held in [[orbit]] around the [[Sun]] by [[gravity]].

===About Newton's Universal Theory of Gravitation===
: Before [[Isaac Newton|Newton]] [[scientist]]s had many different ideas about how [[planet]]s were held in [[orbit]] around the [[Sun]]. Some thought they were held by [[magnetism]] and others thought the [[planet]]s were held in invisible crystal [[sphere]]s around the [[Sun]].
: [[Isaac Newton|Newton]] was the first to realise that the [[force]] which pulls [[object]]s to the ground on [[Earth]] might be the same as the [[force]] that keeps [[planet]]s [[orbit]]ing the [[Sun]] and [[The Moon]] [[orbit]]ing the [[Earth]].

 ===About Newton's Law of Universal Gravitation===
 : '''Newton's Law of Universal Gravitation''' can be used to calculate the [[magnitude]] of the [[force]] acting between two [[mass]]es.
-: '''Newton's Law of Universal Gravitation''' has a similar form to [[Coulomb's Law]] in that both are given with a constant multiplied by a product of some physical property ([[Electrical Charge|charge]] and [[mass]] and [[Inversely Proportional|inversely proportional]] to the square of the [[distance]] between [[particle]]s.

		+
		+	<math>-G</math> is a constant so the left hand side and right hand side are [[proportional]].
		+
		+	<math>m_1m_2</math> is the product of the [[mass]]es.
		+
		+	<math>\dfrac{1}{r^2}</math> is the the [[Inversely Proportional\|inverse]] of the square of the [[distance]].
