LSU pole vaulter Mondo Duplantis soared to a record height of 19 feet, five inches at the SEC Indoor Track and Field Championships. Check out the Physics of a Pole Vault with LSU Physicist David Young.

You need the sprinting ability of a 100 m sprinter, the explosive leg drive of a long jumper, the upper body strength of a weightlifter, the flexibility and twisting skill of a gymnast all in one.

The amount of people pissed that he called the pole a "bar" is hilarious.

I hope to never see someone jump on the bar

Your calculations fail to take into account the energy expended by his core muscles to pull up his legs in the early phase of the vault and his arm muscles to push down against the pole at the final stages of the vault.

I’m hung up right now trying to figure out when they plant the pole, do they try to get it to bend in a certain direction, I think it bulges away from the side where the vaulter is gripping, right?

I would like to add 2 observations to the video:

1 - The name of the tool the athlete uses to vault is pole, not bar. That's why it's called pole vaulting. But, given that bar and pole can be synonyms, it's not entirely wrong; we could also call it a stick for example (like in Portuguese, in which the discipline is called "salto com vara", literally "jump with a stick"). Just that the custom is to call it pole, I guess.

2 - The energy stored in the pole isn't electrostatic, but elastic, because it has to do with the deformation suffered by the pole during the vault execution.

Besides that, I enjoyed the video and find it very interesting and didactic.

Was I the only one that got anxiety at him saying “bar” over and over

I miss pole vaulting, , , a sophomore in high school 13' 6" 1971, , ,

it is not only the kinetic energy that is converted to other forms...it is the push with the legs and rest of body using as a level the pole just before the jump, it is also the stength that is applied to bend the pole, it is also the arms action against the ground thru the pole before the final stage prior attempting to clear the bar
