Question

what is head on collision?

Answer 1

Both the bodies approaching towards each other and collide.

Answer 2

Usually, this means the angle between the two velocity vectors of the two moving objects is zero. This is still pretty ambiguous.

Answer 3

hmm. is there any condition i??like referring to centre of mass and all?

Answer 4

I suppose not

Answer 5

That is another consideration. Like I said, this is ambiguous.

We could define the velocity vectors are being parallel and the center of masses to be co-linear. The line containing both center of masses should also be parallel to the velocities.

Answer 6

are both a and B head on collision?
