Question

(B) In a collision,the relative velocity of approach is defined as $u_{rel} = u_1 - u_2$ and the relative velocity of separation is $v_{rel} = v_2 - v

Vedclass · Accepted Answer

The relative velocity of the first particle with respect to the second after the collision is equal or opposite to the relative velocity before the collision.

Vedclass · Answer

(B) In a collision,the relative velocity of approach is defined as $u_{rel} = u_1 - u_2$ and the relative velocity of separation is $v_{rel} = v_2 - v_1$. The coefficient of restitution $e$ is defined as $e = \frac{v_{rel}}{u_{rel}}$. For an elastic collision,$e = 1$,meaning $v_{rel} = u_{rel}$. For an inelastic collision,$0 < e < 1$,meaning $v_{rel} < u_{rel}$. Thus,the relative velocity of separation is either equal to or less than the relative velocity of approach,which corresponds to the magnitude of relative velocity being equal or opposite in direction depending on the frame of reference and the nature of the collision.
