The instantaneous (reduced) velocity, , is given by Eqn A34 , but even with Eqn A51 , Ē k ( x̄ ) is still a sixth-order polynomial, and hence cannot be easily integrated in Eqn A35...

We filmed strikes with high-speed video, measured strike velocity and used a mathematical model to calculate strike energy...

Furthermore, bipedal running over multiple obstacles is predicted to maintain greater mean sprint velocity compared with quadrupedal running, thereby revealing a potential advantage...

...Pauline Provini; Bret W. Tobalske; Kristen E. Crandell; Anick Abourachid SUMMARY Take-off mechanics are fundamental to the ecology and evolution of flying animals. Recent research has revealed that initial take-off velocity in birds is driven mostly by hindlimb forces. However, the contribution...
