'''Time''' is how long something takes to happen. To '''time''' is to use a [[timerstopwatch]] to find out how long something takes.

: It takes 2 [[Hour|hours]] to drive from [[Birmingham]] to [[London]].

: A [[scientist]] drove to [[London]] from [[Birmingham]] and it took a '''time''' of 2 [[Hour|hours]].

: '''Time''' can be [[measure]]d using a [[clock]] or a [[stopwatch]] or a [[timer]].

'''Time''' is a [[measure]] of how long something takes to happen. ===About Time==='''Time''' can be measured in:*[[Second]]s - Used for quick events like the rate of a reaction.*[[Minute]]s - For slow reactions or journeys of a few miles.*[[Hour]]s - For long journeys or slow changes in [[organism]]s.*[[Day]]s - For gradual changes in [[organism]]s.*[[Week]]s - For changes in a [[human]]s [[mass]] or [[height]].*[[Month]]s - A variable length of time from 28 to 31 days, avoided in science.*[[Year]]s - For the start to [[orbit]]s of other [[planet]]s around stars. : '''Time''' can be [[measure]]d using a clock or a [[stopwatch]]. ==Key Stage 4=====Meaning==='''Time''' is a [[measure]] of the end duration of something happeningan event.

*[[Nanosecond]]s - One billionth of a [[second]], an ultra fast [[LASER]] pulse.*[[Microsecond]]s - One millionth of a [[second]], the [[time]] [[period]] of an [[ultrasound]] [[wave]].*[[Millisecond]]s - One thousandth of a [[second]], the response rate of a tv screen.*[[Second|seconds]] s - Used for For quick events like the rate of a reaction.*[[Minute|minutes]] s - For slow reactions or journeys of a few miles.*[[Hour|hours]] s - For long journeys or slow changes in [[organism]]s.*[[Day|days]] s - For gradual changes in [[organism]]s.*[[Week|weeks]] s - For changes in a [[human]]s [[mass]] or [[height]].*[[Month|months]] s - For seasonal changesA variable length of time from 28 to 31 days, avoided in science.*[[Year|years]] s - For the [[orbit]]s of other [[planet]]s around stars. : '''Time''' can be [[measure]]d using a clock or a [[stopwatch]]. ===References=======AQA==== :[https://www.amazon.co.uk/gp/product/1782946403/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782946403&linkCode=as2&tag=nrjc-21&linkId=32a0abb60dff015b15b50e9b1d7b4644 ''Time (measuring), page 233, GCSE Combined Science Trilogy; Physics, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1782945598/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945598&linkCode=as2&tag=nrjc-21&linkId=ad276ad49df77ab4b40ab4fd0fe10363 ''Time (measuring), page 233, GCSE Combined Science; The Revision Guide, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1782945970/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945970&linkCode=as2&tag=nrjc-21&linkId=a120d24dcc7cc7a58192069a3aafc1d2 ''Time (measuring), page 329, GCSE Physics; The Complete 9-1 Course for AQA, CGP, AQA ''] ====OCR====:[https://www.amazon.co.uk/gp/product/0198359829/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359829&linkCode=as2&tag=nrjc-21&linkId=90e8d7b4f039d53035238fa0320fe00b ''Time, graphs, page 304, Gateway GCSE Chemistry, Oxford, OCR '']:[https://www.amazon.co.uk/gp/product/0198359837/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359837&linkCode=as2&tag=nrjc-21&linkId=3c4229e8b023b2b60768e7ea2307cc6f ''Time, measurement, pages 48, Gateway GCSE Physics, Oxford, OCR '']
