  • Gymnastics is definitely a combination between

  • fitness you have to be in the physical shape in order to do the

  • skills that we do

  • and get through the routines

  • and at the same time make it look effortless

  • so that's kind of like where the artistic side of it comes in too. Especially in

  • college gymnastics it really is a performance you go out there and you want

  • everyone in the crowd to be watching your gymnastics watching your routine

  • The focus is drawing in that crowd

  • cause they...

  • you know you're performing for them

  • and at the same time there is kind of that

  • scientific and technique component you have to

  • put your body exactly in the right place so that you are able to

  • hit those hand stands and stick that dismount

  • With gymnastics there is a lot going on

  • but what we can do is follow her center of mass and make rough approximations for say the

  • force on her feet when she lands and particularly in the case

  • of say, the uneven bars

  • If we follow her center of mass

  • it comes off the bars reaches a peak

  • where her velocity is approximately zero ignoring horizontal velocity

  • Basically what's happened

  • it all of her potential energy at the top has been converted into kinetic energy

  • The force between the gymnast

  • feet and

  • the mat

  • does work to bring the energy of the gymnast to zero. To calculate the work we take the integral

  • of the force parallel to the path over the path traveled

  • If we actually put in the numbers

  • we can calculate a value for this force which

  • turns out to be approximately two or three football players or

  • obviously there is a lot of force there

  • and these gymnasts have to be really strong

  • I remember when i was taking the physics series my sophomore year

  • learning about kinematics and dynamics

  • it definitely would cross my mind

  • think like oh...

  • what are those forces the are going through my legs when I land my vault

  • Or even just

  • you know for every reaction there is an opposite reaction so that when you're

  • pulling the bar down in your giant swings that force down is kinda what sends you

  • back up so you are able to flip twice and then land

  • It is a lot of force

  • by the end of season we know that every single one of the girls on the team are hurting

  • I think that just kinda comes

  • with the nature of the sport.

Gymnastics is definitely a combination between
