Resumen de A Geometric Proof of v2f − v2i = 2ad
In introductory 1-D kinematics, the final and initial velocities (vf and vi) of a particle moving a distance d under constant acceleration a obey the identity:
v2f−v2i=2ad.vf2−vi2=2ad.
(1) This identity is usually proved algebraically. The purpose of this short note is to present a geometric proof—that is, a proof by picture.
