'''Newton's Third Law''' states that "For every [[Action Force|action force]] there is a whenever two objects interact, the [[Reaction Force|reaction force]] with an s they exert on each other are equal in [[magnitude]] but acting and opposite in the opposite direction".

: The two [[force]]s referred to in '''Newton's Third Law''' are on the separate [[object]]s which are interacting.: When an [[object]] "A" exerts a [[force]] ([[Action Force|action force]]) on [[object]] "B" then [[object]] "B" will exert also be exerting a [[force]] ([[Reaction Force|reaction force]]) on [[object]] "A". These two [[force]]s will be equal in [[magnitude]] and opposite in direction.: The terms [[Action Force|"action force"]] and [[Reaction Force|"reaction force"]] may be misleading are sometimes misleadingly used in this context as they simply refer to which [[object]] the observer was interested in first, eg Did the ball hit the head or did the head hit the ball?However, the [[force]]s in such a [[Force Pair|force pair]] do not cause each other, they both exist simultaneously.: Newton's Third Law is related to the law of [[Conservation of Momentum]]. ===Examples===: The [[gravity|gravitational]] pull of the [[Earth]] on [[The Moon]] is equal in magnitude to the [[gravity|gravitational]] pull of [[The Moon]] on the [[Earth]].: The [[gravity|gravitational]] pull of the [[Earth]] on you is equal in magnitude to the [[gravity|gravitational]] pull of you on the [[Earth]]. That is to say that the [[Earth]] is equally pulled towards you as you are to the [[Earth]].: The [[Normal Contact Force|normal contact force]] of a book on a table is equal to the [[Normal Contact Force|normal contact force]] of the table on the book. Both objects exert the same force on one another.: When a rocket expells gas from its engine the [[force]] of the [[gas]] on the rocket is equal to the [[force]] of the rocket on the [[gas]]. ===References=======AQA==== :[https://www.amazon.co.uk/gp/product/019835939X/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=019835939X&linkCode=as2&tag=nrjc-21&linkId=57e96876985fc39b1a3d8a3e3dc238b6 ''Newton’s Third Law, pages 116-117, GCSE Physics; Third Edition, Oxford University Press, 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 ''Newton’s Third Law, pages 169, 170, GCSE Combined Science Trilogy; Physics, 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 ''Newton’s Third Law, pages 201, 202, GCSE Physics; The Complete 9-1 Course for AQA, 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=ad276ad49df77ab4b40ab4fd0fe10104 ''Newton’s Third Law, pages 203, 213, GCSE Combined Science; The Revision Guide, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/178294558X/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=178294558X&linkCode=as2&tag=nrjc-21&linkId=f0dfb66dafcb0c6e9449e7b1a4ae1ac331 ''Newton’s third law, pages 51, 65, GCSE Physics; The Revision Guide, CGP, AQA ''] ====Edexcel==== :[https://www.amazon.co.uk/gp/product/1782945741/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945741&linkCode=as2&tag=nrjc-21&linkId=30da4f2178da182547b62a7329d13b57 ''Newton’s Third Law, pages 152, 154, GCSE Combined Science; The Revision Guide, CGP, Edexcel '']:[https://www.amazon.co.uk/gp/product/1782945733/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945733&linkCode=as2&tag=nrjc-21&linkId=2a2dbec9db6bf5766c0458d908fa0a52 ''Newton’s Third Law, pages 19, 21, GCSE Physics; The Revision Guide, CGP, Edexcel '']:[https://www.amazon.co.uk/gp/product/1292120223/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1292120223&linkCode=as2&tag=nrjc-21&linkId=068ecf40278c32406a7f1c6e66751417 ''Newton’s Third Law, pages 22-23, GCSE Physics, Pearson Edexcel '']:[https://www.amazon.co.uk/gp/product/1292120193/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1292120193&linkCode=as2&tag=nrjc-21&linkId=572df39392fb4200db8391d98ae6314e ''Newton’s Third Law, pages 306-307, GCSE Combined Science, Pearson Edexcel '']:[https://www.amazon.co.uk/gp/product/1782948163/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782948163&linkCode=as2&tag=nrjc-21&linkId=0fdbfd5dd397d6e24a9dfb250f08587f ''Newton’s Third Law, pages 42, 43, GCSE Physics, CGP, Edexcel '']:[https://www.amazon.co.uk/gp/product/1782948163/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782948163&linkCode=as2&tag=nrjc-21&linkId=0fdbfd5dd397d6e24a9dfb250f08587f ''Newton’s Third Law; momentum, page 47, GCSE Physics, CGP, Edexcel '']
