Triple Jump
Triple jump is a sport where you try to jump the farthest for women it is 8.5 meters and for men 11 meters. It has cool rules, equipment, and where it originated from is awesome, some cool facts and it relates to science A LOT.
The rules of triple jump are pretty easy but not the easiest on earth. Some rules of Triple jump are that the amazing athlete has to jump before the takeoff board or the jump does not count. The athlete must land in the sand after the jump. When the athlete is running and about to jump they must hop takeoff and land on the same foot or it is a fault.
Triple jump does not need equipment but it does have some if you want to call it equipment.This might surprise you but you don't need equipment for Triple jump unless you call a takeoff board and sand equipment. In the Olympics it is done indoors and the setting would be a runway, take off board, and sand pit. You don't need many things for this sport. You could call it easy but it's very hard but the athlete practices and their dreams come true and you can do it too.
It originated in the Olympics over a hundred years ago, right? Triple jump first went to the Olympics in 1896 which was 127 years ago. Believe it or not Triple jump was created by the Olympics and has been around for 127 years which was when it first went to the Olympics.
Some really fun facts are cool and others are ok but all of these are epic. The longest triple jump in history was actually 18.29 m (60 feet) and that was done by Jonathan Edwards. The female longest is 15.74 m (51 feet 71/2 inches) and that athlete was Yulimar Rojas Venezuela. Now that is impressive.
Newton's first law of motion (inertia), believe it or not, has a big part in Triple Jump. Newton's first law is amazing; it is about inertia. An object at rest remains at rest, and an object in motion will stay at motion until acted upon by an unbalanced force. And that is Newton's first law of motion.
There are balanced and unbalanced forces. The first one is balanced like you are just standing. A balanced force is when something is moving and the other is also moving and they are moving toward each other and they are not moving because they are at the same amount of force. Like when two kids the same size are on a seesaw and they didn't push off the ground they would be level.
The next one is unbalanced like you are jumping and JUST STAY THERE it's weird. An unbalanced force is when one thing is moving and the other one is not moving they would both move because one is using more force than the other. Let's say an adult and a small child were on a seesaw and didn't push off the ground. The adult would be on the ground and the child would be at the top.
Balanced forces in triple jump
They used a balanced force at the start where they use a friction force on the ground when they are getting ready to run.
In triple jump there are als unbalanced and balanced forces. This time let's start with unbalanced. An unbalanced force in triple jump would be when the athlete is running and doing the triple jump the forces are muscle force, and gravitational force.
Objects at rest means they are not moving until something moves it; it's also in triple jump. In triple jump there are three things at rest that I can think of: the sand while the athlete is not on it, the track also when the athlete is not moving on it, and finally the athlete themself while they are getting ready to run and jump.
Objects at motion in triple jump are the same as at rest but moving until something stops it. Again only three I can think of and they are: the sand when the athlete is on it, the track might be moving a tiny bit while they are running, and finally the person running and jumping.
When objects at rest no longer are at rest, this means that something is moving now that another object moved it. When the person is getting ready to run and jump then hits the sand.
When will the objects in motion no longer be in motion it is still the same thing but the opposite, the object moving stops from another object stops it. When the athlete is jumping and then hits the sand then stop or at least slow down.
Newton’s second law is F=M×A which also means Force= Mass×Acceleration.
What is force, force has a lot of weird rules that it made. Force is something that moves, stops or changes direction by another force or object/noun. In triple jump forces are contact forces when they jump and hit the track or sand. And another force is a muscle force by changing positions in the jump to get longer in order to get a long jump. These two forces really help the athlete.
Mass is a quantitative measure of inertia or in kid/fourth grade words it is how much matter/stuff is in something like if I said which has more mass/matter/stuff in it you or a giant balloon if you said balloon… you're wrong it is actually you because the balloon particles/air/adams are more spread out than you, you are more dense than the balloon which is less dense. In triple jump the mass is the athlete because they weigh more than a lot of objects that are there.
Acceleration is when you are running and then you slow down for some reason that is deceleration, the acceleration for slowing down can you guess what acceleration is… it is when you speed up, slow down (even though it is called deceleration) or change directions. Like when you are running slowly then speed back up its acceleration. In triple jump they accelerate when they get ready to run and jump and then start and speed up. They decelerate when they jump to the sand then hit it and slow down.
How force impacts the acceleration of different masses. The force(muscle force) when they are running slower than usual they don’t run as fast which means they don't jump as far. The athlete will want to use a lot of force because if they don't go as fast they won't jump as far and the whole point of triple jump is to jump far… and to do three different jumps.
How athletes predict the acceleration of the objects in triple jump based on the masses and forces. At the last jump to the sand because they would want to go the farthest out of everyone. When the athlete tries to jump at the end they want to jump far, the farthest out everyone.
Newton's 3rd law, any action has an equal and opposite reaction. So let's say that you jump on a trampoline and What is the action. An action is when you run or jump or something that you do and any kind of force any kind of action is called a verb meaning it shows a action(something you do).
Actions in triple jump, the actions are big. In Triple Jump some actions are that they are jumping or running. Running because you jump and come DOWN the trampoline goes down (equal reaction) then it comes back up (opposite reaction) with you too.
