So, what if we broke down the high‑jump into a simple physics problem—speed, take‑off angle, and gravity—and then we could predict exactly how high a pros or a casual friend could clear. Sounds like a challenge, right?

Sure, but first we need a motion equation, a data sheet, and a way to validate the assumption that human joints can produce 2.5 m. Let's set up the experiment.

Fine, but let's be clear: if you want to brag, you better also brag about the errors you made when you measured. We'll need to record the exact start and end times, the take‑off angle in degrees, and the exact height reached with a calibrated meter stick. Don't forget to double‑check the stopwatch's drift. Then we can separate the real physics from the bravado. Let's do it.
