FormulaMaximum height = velocity**2/(2*gravity); Time to apex = velocity/gravity; Same-height airtime = 2*velocity/gravity

Worked example

Inputs

Initial vertical speed
10 units/s
Downward acceleration
20 units/s²

Expected results

Maximum height
2.5 units
Time to apex
0.5 s
Same-height airtime
1 s

How to use this tool

  1. Tune an ideal vertical jump with constant downward acceleration.
  2. Set initial vertical speed, downward acceleration in the indicated units.
  3. Calculate and compare maximum height, time to apex, same-height airtime.

Try this example

{
  "velocity": 10,
  "gravity": 20
}

Accuracy and scope

Idealized educational model. Enter measured values in the displayed units; real systems may require additional corrections. User-defined game-rule arithmetic; no current game mechanics or search-volume claims.
