  • The Physics of Horse Jumping By Hanna Mendola
  • Horse Force???
    • When jumping, a horse’s force depends on their back legs and the speed they are going at. Lets say a horse was walking and it tried to go over a 5 foot tree stump. Could you do that??? NOPE!!! Think logic.
  • Would Bigger or Smaller Horses Be Better?
    • Bigger of course! The bigger horse has more force in its back legs that that little pony. Sorry, but no matter how tiny and cute those ponies are, they just won’t do. 
  • Newton’s Second Law
    • When a horse is jumping, it relies to Newton's Second Law, due to it’s mass. For more info, check out slide #2
  • Balance…
    • When jumping, a rider gets into a standing position called 2-point to balance the weight, as you see in this picture.
    • When the rider leans forward, the weight is balanced so the horse doesn't have to carry its self and the rider.
  • Speed!
    • As I mentioned in the second slide, speed matters. If a horse was traveling at a canter (like a really fast run for humans) the horse would have more force and jump higher. If the horse was trotting, (jogging) it would probably step over it instead of jump whatever it was trying to jump.
  • We got the basics,
    • Who’s up to a review???
    • When a horse is trying to go over a 5 foot jump, which gait would be better?
    • A. WALK B. TROT C. CANTER
    • True or false
    • When going over a jump you sit in the saddle.
    • True or false
    • Horses use their back legs to propel themselves over a jump.
  • Answers
    • Q # 1 C. Canter
    • When a horse is going over a jump it has more force by using more speed
    • Q # 2 False
    • The balance will go away, and you and the horse will be on the ground in no time!
    • Q # 3 True
    • A horse’s force depends on it’s back legs
  • Okay… Back to the Point
    • When I preformed my experiment, I jumped three horses! The first one, the biggest, Lincoln, he jumped the highest because of his mass. The next one was Gracie, a larger pony, and she skidded over the jump. The last horse was Bruce, the fastest, a bit smaller than Lincoln, (he is pure thoroughbred).
    • He jumped it very well. Not to high, not to low. YAY!
  • Data… The horse probably started out fast, then stumbled and went VERY slow at the end.
  • Data… The horse probably went slow until it saw the jump, decided to go fast, and then slowed when it went over the jump.
  • Data… When the horse jumped, it’s speed probably decreased when it jumped the jump, then it sped up again.
