https://www.physicsforums.com/attachments/221718 Say if we have two particles P, and Q, traveling at velocities Vp and Vq respectively. If it is IMPOSSIBLE for Q to collide with P, let us find the distance of closest approach. So from the frame of reference of P, itself is stationary, and Q is moving at Vqp (velocity of q relative to p). In order to get the closest to P, the velocity of Q (Vq) can take a locus of velocities, forming the shape of a circle of radius mod(Vq).
Why is it that in order for Q to get the CLOSEST to P, Vqp has to be tangential to Vq from the circle?This is in 2 dimensions, and by collide, I mean intercept
