==Key Stage 3==
===Meaning===
[[Mass]] is the amount of [[matter]] that something is made of, [[Measure|measured]] in [[Kilogram|kilograms]]. ===About Mass===: '''Mass''' can be measured using a [[Measuring Scale|measuring scale]].: The more [[mass]] an [[object]] has, the harder it is to [[accelerate]] the [[object]].The [[unit]]s of [[mass]] you should be able to use are:*[[Kilogram]]s: For [[object]]s that can be lifted by [[human]]s.*[[Gram]]s: For quantities of [[chemical]]s used in a [[Chemical Reaction|chemical reactions]]. ==Key Stage 4 Foundation=====Meaning===[[Mass]] is the amount of [[matter]] than that something is made of, [[Measure|measured]] in [[Kilogram|kilograms]]. ===About Mass===: '''Mass''' can be measured using a [[Measuring Scale|measuring scale]] or [[Electronic Balance]].: The [[SI Unit]] of [[mass]] is the [[kilogram]].: [[Mass]] is a [[scalar]] quantity as it has [[magnitude]] but does not have a direction.: The more [[mass]] an [[object]] has, the harder it is to [[accelerate]] the [[object]].The [[unit]]s of [[mass]] you should be able to use are:*[[Megagram]]s: Also known as [[ton]]s. There are 1000kg in one [[megagram]].*[[Kilogram]]s: For [[object]]s that can be lifted by [[human]]s.*[[Gram]]s: For quantities of [[chemical]]s used in a [[Chemical Reaction|chemical reactions]]. There are 1000g in 1 [[kilogram]].*[[Milligram]]s: For doses of [[medicine]]. There are 1000,000mg in a [[kilogram]].*[[Microgram]]s: For [[Vitamin]]s and other [[micronutrient]]s. There are 1000,000,000µg in a [[kilogram]]. ==Key Stage 4 Higher=====Meaning==='''Inertial mass''' is <math>mass = \frac{Force}{acceleration}</math>; the [[ratio]] of [[force]] to the [[acceleration]] of an [[object]]. ===About Inertial Mass===: '''Mass''' is the resistance of an [[object]] to being [[accelerated]]. The greater the [[mass]] the more [[force]] is needed to [[accelerate]] it.: '''Mass''' can be measured using a [[Measuring Scale|measuring scale]] or [[Electronic Balance]].: The [[SI Unit]] of [[mass]] is the [[kilogram]].: [[Mass]] is a [[scalar]] quantity as it has [[magnitude]] but does not have a direction.The [[unit]]s of [[mass]] you should be able to use are:*[[Megagram]]s: Also known as tons.

There are 1000,000,000µg in a [[kilogram]].*[[Nanogram]]s: The [[mass]] of [[Cell (Biology)|cells]] in [[organism]]s. There are 1000,000,000,000ng in a [[kilogram]]. ===Equation===''NB: You need to remember this equation.''
