Question

In a head-on collision between two particles, is it necessary that the particles will acquire a common velocity at least for one instant?

Answer 1

Answer:

no I don't think so .................

Answer 2

Yes, a common velocity is acquired by the particles at least for one instant of time.

Explanation:

• When in two particles, there is a head-on collision, it is mandatory that a common velocity is acquired by the common velocity for one instant at least.
• When it comes to the elastic collision, after this instant, there will be the separation of the particles, which move with various velocities.
• When it comes to inelastic collision, the particles will stay together and move with a mutual speed.
