PE Revision Test
1.Force summation is...Using as many body parts as possible and moving small mucles last to get maximum power.Or large mucles for power small mucles for accuracy and direction.
2.Projectile motion has 3 factors impacting the projectiles distance what are they
Speed of realese Angle of realese Height of realese
3.Balance and stability are impacted by
BOS Base of support Width and points of contact
COG Centre of gravity High vs low and shifting What do they stand for
VLG Verticle line of gravity Always runs through the centre of gravity
4.Newtons laws-there are 3 what are they give sporting examples for each Inertia-If you kick a ball it will keep rolling till an outside force stops it. F=ma. Action/Reaction-If you bounce a ball on the ground it will bounce back up.

Observing the Effects of Surface Area on Reaction Rate
Aim: To make simple observations during a reaction between calcium carbonate CaCo3 chips and powder with hydrochloric acid HCI
Equipment:Boiling tube calcium carbonate chips and powder with hydrachloric acid measuring cylinder spatula
Method:
1:Measure 2ml of hydrochloric acid and pour this into your boiling tube.
2: Holding your boiling tube over a sink of heatproof mat add a pea-sized amount of calcium carbonate powder to your boiling tube.Record your observations below.
3:Repeat the experiment but this time use a chip of calcium carbonate that is roughly the same size as the spatula of powder you used previously.Record your observations below.
RESULTS
When using powder it fizzed up.
When using the rocks it bubbled.
CONCLUSION
In conclusion the more reactants there is the faster the reaction will happen or the more surface the faster the reaction occured

Good and Bad Coaching PE
The first coach was coaching his team very very aggresivly and wouldnt listen to his team he also swore at them and made them feel like shit.He also had a go at the refs as if it was a professional game.The coach was unsuccesful his team was losing and feeling like shit at the same time.Alot of the players ended up sad and looking at the ground in shame.The second coach was alot more succesful in the training he connected with his team made them feel good he had a good tone of voice and asked his team questions and gave them feedback and at the same time was helping his team have fun and gain alot of skills in the process.His athletes responed by happily listening to him and following the drills while having fun and smiling.In Conclusion the second coach was alot better because he talked sense and gave good constructive feedback not just yelling a bunch of random stuff a his team like the first coach.He alos helped the kids have fun while learning which is the main thing you must do as a coach in junior sport as it helps them enjoy the sport and hopefully they continue to play the sport and if they wish make a career from it.

Book/Movie Title: Floyd Mayweather "Full Mayweather Documentary -Biography Channel
Author/Director: Showtime Boxing and Biography Channel
Text Type:Documentary
Date Finished: April 12th 2017
Floyd Mayweather " Full Mayweather Documentary is a biography about the living boxing legend Floyd Mayweather Jnr also known as Floyd money Mayweather. The documentary is about how the boxing legend grew up and where he is in his career and life today.
Floyd Mayweather is a interesting person because like everyone who makes it big in the fight game worked hard and sacrificed a lot to get all the money and titles he has today. But he was also gifted with a personality that suits a fighter and has helped him to make 600 million dollars and counting over his career his personality is cocky an example of when he is being cocky during the documentary is when he is trash talking opponents in the middle of fights and when he enters the ring in one of his fights with people carrying him while hes dressed as a king.Floyd is also brash and always bragging about money and flashing tens of thousands of dollars around and driving around in supercars this causes people to either hate him or love him.But despite all of his antics and showing off Floyd is a real inspiration he grew up poor with his Dad in jail and his Mum addicted to drugs but still became the top boxer in his era .Floyd also proves you can work hard behind the scenes putting in blood sweat and tears but then still have a lot of fun doing whatever you like whenever you like.
Floyd Mayweather and the way he lives his life has a personal impact on me and other young aspiring fighters because he worked extremely hard to get to where he is not having much money so he couldn't do stuff he wanted to but now he has the money to do fun things and buy cool cars and nice houses and he can support his family.Floyd Mayweather is an inspiration to me because he worked hard and now he gets all the benefits of his hard work and he still works hard in the gym everyday doing 8 mile runs and 12 rounds of sparring along with bag work pad work and strength and conditioning and he does all this even with all the distractions in his life.He he also proves if you work hard you can do the things you want and he proves you can have fun while working hard.This helps me in my life knowing that i need to work hard but sometimes i can take a break and have some fun.

Book/Movie Title: Warrior
Author/Director: Gavin O Connor
Text Type: movie
Date Finished:Friday March 31st 2017
Warrior is a sports drama movie about 2 brothers Tommy Conlon and Brendan Conlan who split up when they were teenagers Tommy left with his mother and Brendan stayed with his alcholic father and his girlfriend turned wife.But only a few years after the family split up Tommy and Brendans mother died of cancer but Brendan and his dad never found out that she died because Tommy hated them so much he didnt tell them and they had lost contact.But then 30 years later the family met up again Tommy coming back from war where he lost his best friend and promised his friends wife and kids money and he hired his now recovering alcholic father to coach him for the biggest MMA tournament in history Sparta for 5 million dollors.And Brendan had quit fighting as well and had 2 kids and his wife but they got in financial trouble and brendan started fighting again in night clubs for money behind his wifes back so they didnt lose there house but then he loses his job as a physics teacher for doing the fights and then starts training full time and when one of his teammates who was in Sparta gets injured his coach and long time friend gets him into the tournament.To help him keep his house if he wins.Both the brothers go into the tournament as under dogs and end up in the final together in a thrilling fight scence where they are both crying remebering the things they went through together as kids but in the end Brendan wins the 5 million dollor prize.The final shot of the movie is the 2 brothers walking out of the arena hugging each other and there dad smiling showing the family may have reunited in the most unlikely of ways.
The character that got me hooked to the movie the most is Tommy because he went through so much struggle in his life but still found ways to help people by joining the army and saving a entire group of U.S soilders he didnt even know.The respect fellow soilders have for Tommy is shown when he enters the cage and a whole area of the arena is U.S soilders singing songs in his honour.He also shows through all the pain hes suffered he is willing to enter a MMA tournament for 5 million dollors and give the money to his fallen friends family. The soilders singing songs in his honour and Tommy becoming an instant fan favourite in amongst MMA fans shows us the respect the public has for Tommy and what he is able to do.I feel the reason why people love tommy so much in the movie is everyone likes to see a hero and wants someone to look up to and Tommy is easily that hes a war hero who defended his country and saved many lifes and also a successful hard working athlete that i can look up to knowing no matter where you come from or what youve been through you can persivere and reach greatness and inspire other people to reach greatness changing lifes in the process.
The Movie is relevant to students my age because as young people we all have dreams and goals and we all want to do something great in life but some people think just because you dont grow up in the richest and nicest area with the best circumstances you cant reach these goal and make dreams reality.But this movie shows through what the 2 brothers went through growing up with a alcholic father and their parents spliting and the brothers not seeing each other again until 30 plus years later when they are aboun to fight in a cage and their mum passing away shows us that no matter how bad your circumstances are you can still reach your goals work your way out of any situation and make dreams a reality.
