WebThe motion is initiated when body weight is applied to the foot at the dome of the talus while floor contact is still at the tip of the os calcis. An unstable lever results from differences in bone length between these points. Strong action by the pretibial muscles retards the terminal arc of ankle plantar flexion, so forefoot contact is gradual. Web20 May 2016 · Here are the 10 equations you should have in mind if you are working on ballistics. 1. Escape Velocity. Escape velocity is the speed at which the kinetic energy plus the gravitational potential energy of an object is zero. It is the speed needed to “break free” from a gravitational field without further propulsion.
