All ball of mass $ m_{1} $ collides elastically and head on with another ball of mass $ m_{2} $ initially at rest. In which of the following cases transfer of momentum will be maximum?
Updated On: Feb 5, 2024
- $ m_{1}>m_{2} $
- $ m_{1} < m_{2} $
- $ m_{1}=m_{2} $
- Cannot be predicted
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Transfer of kinetic energy and hence, momentum is maximum when $ m_{1}=m_{2}$ .

Top Questions on Elastic and inelastic collisions
- Two particles, 1 and 2, each of mass 𝑚, are connected by a massless spring, and are on a horizontal frictionless plane, as shown in the figure. Initially, the two particles, with their center of mass at \(𝑥_0\), are oscillating with amplitude 𝑎 and angular frequency 𝜔. Thus, their positions at time 𝑡 are given by \(x_1 (t) = (x_0 + d) + \alpha \ sin \omega t\) and \(x_2t = (x_0 -d) − \alpha sin \ wt,\) respectively, where \(𝑑 > 2𝑎.\) Particle 3 of mass 𝑚 moves towards this system with speed 𝑢0 = 𝑎𝜔/2, and undergoes instantaneous elastic collision with particle 2, at time \(𝑡_0\). Finally, particles 1 and 2 acquire a center of mass speed \(𝑣_{cm}\) and oscillate with amplitude 𝑏 and the same angular frequency 𝜔.

Concepts Used:
Elastic and Inelastic Collisions
Elastic Collision:
According to elastic collision, the kinetic energy of the system will remain constant which means there will be no change in the kinetic energy of the system before and after the collision. It also goes along with the conservation of momentum.
Examples of Elastic Collision
- While playing billiards, balls hit each other.
- A ball is thrown and is bounced to the same height it was thrown from, is an example of elastic collision as there is no net change in the kinetic energy.
- The collision of atoms is also an elastic collision.
Inelastic Collision:
According to inelastic collision, the kinetic energy of the system is not conserved, unlike inelastic collision. The kinetic energy is lost as it gets debauched in other forms of energy like heat, sound, etc, or is absorbed by the body. But they go after the conservation of momentum, like an elastic collision.
Examples of Inelastic Collision
- When the ball is dropped on the ground, it fails to reach the height it was dropped from.
- The accident of two vehicles is an inelastic collision.
- If the clay is thrown at a wall, it sticks to it.
