Olympic Modern Pentathlon
The modern pentathlon is a five competition olympic sport. It started in 1912 and is ment to reflect the duties of a cavalry soldier. Of course the newer age has altered things a bit. The first pentathlon consisted of the long jump, javelin throw, discus throw, a short foot race and wrestling but after a while these values of a cavalry soldier seemed obsolete so they were then replaced by pierre de coubertine` with fencing, swimming, horse jumping, pistol shooting and lastly running.
The first course is one touch epee fencing the contestants are randomly grouped with another person then begins the fight.
If the one person wins the fight they move on to the next highest ranked contestant. After there is only one more round the highest two ranked contestants fight the winner is then the winner of the round.
Next is a 200m swimming contest. Honestly it does not get more simple then that is literally a 200 meter freestyle swim the winners of that goes to the next round.
Next is horse jumping. You go on a horse you have never been on before
Next you have to navigate through a series of jumps with your horse.
Next is pistol shooting, but it is not a real gun it is just a laser pistol that senses where the bullet would have gone if it was real.
Lastly is the run. You go on a run based on the shooting round then the winner of all of those is the gold medalist. But sometimes they can be added together.
FAMOUS PENTATHLON OLYMPIEN: General George S. Patton(yes that one) was the first American in the modern pentathlon.
Newton's first law is very influential in this sport. Like “an object in motion will stay in motion unless acted upon by
an external force” can be an example since the laser bullet will keep on moving until the board stops it. Also, the bullet will not move unless the trigger shoots it. And in horse riding the horse has potential energy because it wants to move but it has restraints then when they are released it has kinetic energy flowing through the course. And the swimming cause it has buoyant force flowing through the swimmer.
Newton’s second law is also influential in this sport because there is a lot of moving in all the segments. So Newton's second law is the more mass an object has the more force it needs to be accelerated. But this is very conflicting because mass does not just mean how heavy something is, it is also the density and placement of gravity. Examples:
FENCING: When performing a lunge with a french grip epee you need to have all acceleration in your legs and mass in swords and force in arm.
SWIMMING
When performing a backstroke you need all acceleration in legs, all mass in well nothing really it needs to be evenly distributed And all force in hands.
HORSE RIDING
The horse needs gravitational force and muscular force to go over the jumps and to go down or else it would just go up forever.
SHOOTING
The bullet(laser) is VERY light so it needs very little acceleration to move and it needs contact force to stop it.
RUNNING:
The runner needs a lot of acceleration to speed down the track; he also needs to divert all mass to the legs.
See Newton's second law is very influential in the modern pentathlon!
Newton's third law is probably the most famous of the three laws because it makes the most sense(well to me)ever hear the sentence every action has an opposite reaction. That's the third law: it means every thing or force you do it will always exert either that amount of force or something else. Depending on the mass but as all the laws it depends on SETTING you can't have the same amount of force on the moon than there is on the earth and expect to go 1 foot! Also the acceleration can affect it because that does not apply in some cases. That's Newton's third law of motion.
