![Page 21: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/21.jpg)
BOS, COS & LOG•Using the terms (base of support, centre of gravity
and line of gravity) describe how sumo wrestlers (or athletes in general) could increase their stability?
Increase the size of their
BOS
Lower their COG
Keep their LOG within their BOS
![Page 22: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/22.jpg)
Force Summation•Definition
The sum of all forces generated by each body part.
•Three principles
oUse the maximum amount of body parts possibleoSequence (large muscles groups first, small muscle
groups last but fast)oTiming (contracting muscles at the optimum point of
contraction
![Page 23: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/23.jpg)
Principles of Force Summation…
•Use the greatest number of body segments or muscle groups as possible.
• In the correct sequence, use large muscle groups first and then the small muscles last, but fast.
•Use the correct timing of the body segments or muscle groups.

Newton’s Laws of Motion•Law 1:▫ Inertia
•Law 2: ▫Acceleration
•Law 3: ▫Action/Reaction
![Page 25: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/25.jpg)
Explain one ‘Law of Motion’ in detail
•Pick one law of motion.
•Using this image, explain how the law of motion could be
applied to this sporting example.
•Tell your neighbour.

Law 1: InertiaLaw 1: Inertia- an object remains at rest or in motion unless acted upon by an external
force.
![Page 27: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/27.jpg)
Law 1: Inertia• Inertia is an objects resistance to change in motion.
An objects inertia is proportional to it’s weight (mass).
•The heavier the object, the more inertia it has.
•Sporting example…

![Page 30: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/30.jpg)
Law 2: Acceleration• Law 2: Acceleration- the acceleration of an object is
dependant on the mass, size and direction of the force acting upon it.
• force = mass x acceleration [ f = m x a ]
![Page 31: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/31.jpg)
Law 2: Acceleration•When a force is applied
to an object, it will move in the direction the force was applied.
• Depending on the size/ mass of the object, it will accelerate accordingly. ▫The smaller the object
the faster it will accelerate.
▫The larger the mass, the slower the acceleration.
![Page 32: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/32.jpg)
Law 3: Action/Reaction
• Law 3: Action- reaction- whenever a force is
applied there is an equal and opposite reaction.
![Page 33: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/33.jpg)
Law 3: Action/ Reaction• If an athlete exerts a force
onto the ground in order to push off, the ground will exert an equal and opposite force on the athlete, pushing them up into the air.
•Action force
•Reaction force
![Page 34: Revision Lessons](https://reader035.fdocuments.us/reader035/viewer/2022070501/5681693c550346895de0b4a6/html5/thumbnails/34.jpg)
Example- Swimming•Think about a swimmer:
a) When would Newton’s 3 laws take place?
b) How could Newton’s 3 laws of motion help their performance?
