The Physics of Gymnastics
Transcript of The Physics of Gymnastics
After you flip off the vault and are in the air, you will stay in motion until gravity (outside force) pulls you down. When you jump up to grab the uneven bars, you will stay in motion unless an outside force (the bars) stops you.
When you get ready to dismantle from the bars, the outside force of gravity pulls you down. When you stand on the beam, you are at rest. You will stay at rest until an outside force stops you.
When you are done with your routine and dismantle the beam you will stay in motion until gravity pulls you down. Vault Uneven Bars Beam When you go to flip on the vault, the more mass the gymnast has and the faster they run equals the force.
Mass: 150 kilograms
Acceleration: 10 m/s
Force = 1,500 N When you jump to grab the bars, the more mass the gymnast has and the more acceleration equals the force.
Mass: 170 kilograms
Acceleration: 20 m/s
Force = 3,400 N When flip mount on the beam the more mass the gymnast had and the more acceleration they had equals the force.
Mass: 125 kilograms
Acceleration: 8 m/s
Force = 1,000 N Newton's 3rd Law For every action there is an equal and opposite reaction. Vault Uneven Bars Beam When a gymnast presses on the vault the vault presses back on them with an equal force.
A gymnast pushes off the vault with a force of 20 N.
The vault pushes back on her with 20 N. When a gymnast is on the bars, she/he presses and holds onto the bars. Doing this they exert a force onto the bars and the bars push back on them.
A gymnast holds onto the bars with a force of 15 N.
The bars exert an equal force of 15 N back on her. When a gymnast presses on a beam, the beam presses back on her/him with an equal force.
A gymnast presses on the beam with a force of 7 N.
The beam pushes back on her/him with an equal fore of 7 N. Beam Uneven Bars Vault "Explaining the Uneven Bars in Gymnastics." iSport. iSport. 18 February. 2013. <http://gymnastics.isport.com/gymnastics-guides/explaining-the-uneven-bars-in-gymnastics>
