: [[Gravity]] is a [[Non-contact Force|non-contact force]] because it can act without [[object]]s touching.

: All [[object]]s are affected by [[gravity]].

: [[Isaac Newton]] was the first to realise that [[gravity]] is the [[force]] that holds the [[planet]]s in [[orbit]] around [[The Sun]].

: The [[force]] of [[gravity]] between two [[object]]s is always equal in [[magnitude]] but opposite in direction.

| style="height:20px; width:200px; text-align:center;" |[[Object]] A has 1[[kg]] of [[mass]] and is [[attract]]ed to [[object]] B. [[Object]] B has 2[[kg]] of [[mass]] and is [[attract]]ed to [[object]] A. The [[force]] acting on [[object]] A is the same as the [[force]] on [[object]] B.
