free fall

when a falling object is free of all restraints - no friction, with the air or otherwise - and falls under the influence of gravity alone

equation for v

v = at

equation for instantaneous v of object falling from rest

v = gt

equation for v of object that is thrown upward

v = initial velocity + at

equation for v of object thrown downward

v = initial velocity - gt
