Glancing Collision:

A glancing collision is a type of collision in which two objects collide with each other at an angle, resulting in a change in their direction of motion. It is characterized by a tangential impact between the two objects, causing them to move off in different directions after the collision.

Necessary Conditions:

To have a glancing collision between two objects, the following conditions need to be met:

1. Non-central collision: The collision should occur at an angle other than 0 degrees or 180 degrees. In other words, the objects should collide tangentially rather than head-on.

2. Conservation of momentum: The total momentum of the system (the two colliding objects) should be conserved before and after the collision. This means that the vector sum of the momenta of the objects in both magnitude and direction should remain constant.

3. Conservation of kinetic energy: The total kinetic energy of the system should be conserved before and after the collision. This implies that the sum of the kinetic energies of the objects should remain constant.

4. No external forces: There should be no external forces acting on the system during the collision. This condition ensures that the collision is isolated from any external influences that could affect the outcome.

5. Rigid bodies: The objects involved in the collision should be considered as rigid bodies. This assumption allows for a simpler analysis of the collision, as it neglects the deformations that may occur during the impact.

Conclusion:

A glancing collision is a type of collision where two objects collide tangentially, resulting in a change in their direction of motion. The necessary conditions for a glancing collision include a non-central collision, conservation of momentum and kinetic energy, absence of external forces, and consideration of rigid bodies. By satisfying these conditions, one can analyze and understand the behavior of objects involved in a glancing collision.

Glancing collision is a collision that takes place under a small angle, with the incident body being nearly parallel to the surface.Collision at glancing angle is called “glancing collision”. Collision: Object is deflected after the collision withthe surface. The angles between the body and the surface normal areindicated as α and β. The angles between the body and the surface are 90 – α and 90 – β.
