Jumping on the force plate you can feel the force. We use time of flight method to estimate the height of the jump.

$s=s_{0}+v_{0}t+{\tfrac {1}{2}}at^{2}$ and thus we have $h=v_{0}t-{\tfrac {1}{2}}gt^{2}$ because $h_{0}=0$ and $a=-g=-9.81m/s^{2}$ .

Also take-off velocity is easy to calculate as a difference.
