===About Force Multipliers===
: A '''force multiplier''' can be used to lift things that are too heavy to lift with your hands.
: There are three two main '''force multipliers'''you should know:*Levers[[Lever]]s*Gears[[Gear]]s*Pulleys[[Pulley]]s {| class="wikitable"|-|[[File:Lever.png|center|400px]]|-| style="height:20px; width:400px; text-align:center;" |A lever makes it easier to lift a heavy object.|} {| class="wikitable"|-|[[File:Pulley.png|center|400px]]|-| style="height:20px; width:400px; text-align:center;" |A pulley can make it easier to lift an object.|} ==Key Stage 3=====Meaning===A '''force multiplier''' is a tool that increases the size of a [[force]] by reducing the distance the [[force]] moves through compared to the original [[force]]. ===About Force Multipliers===: A '''[[Force]] can be multiplied''' due to [[Conservation of Energy]]. Since [[Work Done]] = [[Force]] x [[distance]] then a tool can make the [[force]] larger by making the [[distance]] shorter.: There are four main '''force multipliers''' you should know:*[[Lever]]s*[[Gear]]s*[[Pulley]]s*[[Hydraulic System]]s ===References===:[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 ''Force multipliers, pages 86, Gateway GCSE Physics, Oxford, OCR '']
