In one dimensional elastic collision of equal masses, the velocities are interchanged. Can velocities in one dimensional collision be interchanged if the masses are not equal?

In one dimensional elastic collison of equla masses, the velocities are interchanged. Can velocities ina one dimensional collision be interchanged if the masses are not equal?

In a head on elastic collision of two bodies of equal masses

Consider the following statements A and B. Identify the correct choice in the given answers A. In a one dimensional perfectly elastic collision between two moving bodies of equal masses the bodies merely exchange their velocities after collision. B. If a lighter body at rest suffers perfectly elastic collision with a very heavy body moving with a certain velocity, then after collision both travel with same velocity.

Considering equal mases, get the expressions for the velocities of bodies after the collision.

In an elastic one dimensional collision between two particles the relative veloctiy of approach before collision is

Discuss elastic collision in one dimension. Obtain expressions for velocities of the two bodies after such a collision.

In figure, determine the character of the collision. The masses of the blocks, and the velocities before and after are given. The collision is

From study of elastic collision we understand that if two colliding particles have equal masses they interchange their velocities and energy transfer is maximum if they have equal masses and one is at rest w... other. This principle can be easily used in nuclear reactor to select a moderator. If m_(1)=m_(2)=m and m_(2) at rest then m_(1) will stop after colliding with m_(2) and m_(2) will move with velocity of m_(1) . In case of nuclear reactor we used a moderator such that neutrons can be slowed down. With above reference answer the following questions Which is correct statement

The dimensional formula of velocity gradient is

Statement I: If a sphere of mass m moving with speed u undergoes a perfectly elastic head-on collision with another sphere of heavier mass M at rest ( M gt m ), then direction of velocity of sphere of mass m is reversed due to collision (no external force acts on system of two spheres). Statement II: During a collision of spheres of unequal masses, the heavier mass exerts more force on the lighter mass in comparison to the force which lighter mass exerts on the heavier one,
