What Is A Collision?
Collision: When two bodies are approaching each other, a force comes into play between them for a finite time and brings about a measurable change in their velocities, momentum and energy according to the respective laws of conservation, a collision is said to have taken place. However, in physics, it is clearly understood that collision…

What Do You Mean By Elastic Collision?
Elastic collision ( or elastic scattering): If the sum of the kinetic energies of the colliding particles or bodies after collision is the same as the sum of the kinetic energies of the colliding particles or bodies before collision, then the collision is said to be elastic collision. In this type of collision the internal…

What Do You Mean By Inelastic Collision?
Inelastic collision (or inelastic scattering): If the sum of the kinetic energies of the colliding bodies or particles after collision is not the same as the sum of the kinetic energies of that colliding bodies or particles before collision, then this type of collision is said to be inelastic collision. Most type of collisions which…

Define Conservation Of Linear Momentum.
Conservation of linear momentum: Let us consider two masses and moving with velocities and respectively, collide in an inertia frame of reference. Let and be the velocities of the particles after collision respectively. When no external force acts on the particles then their total linear momentum is conserved. Therefore, This relation holds good for elastic…

Explain The Two Types Of Inelastic Collision.
Two types of inelastic collision: If the sum of the kinetic energies of the colliding bodies or particles after collision is not the same as the sum of the kinetic energies of that colliding bodies or particles before collision, then this type of collision is said to be inelastic collision. So there are two possibilities, either…

Define Reaction.
If the final particles after collision is entirely different from the initial particles before collision, then this type of collision is known as reaction. The initial particles are known as reactants and the final particles are known as the products. Since the interacting particles are isolated and no external torque acts on the system so…

What Is The Advantage Of Studying The Collision Process?
Advantages of studying collision process: There are various types of forces and interactions in the nature. These forces and interactions act in both the macroscopic and microscopic levels. Therefore the study of collision which is actually the relative motion between two colliding particles, helps us to understand the basic characteristics and nature of the interactions…

Explain Laboratory And Centre Of Mass Frame Of Reference.
In order to study the collisions between two particles, we shall come across the centre of mass system or centre of mass frame of reference and laboratory system or laboratory frame of reference. A reference frame is the space and this space is determined by a rigid body, which is known as base. The rigid…

What Is The Advantage Of Studying A Collision Process In The Centre Of Mass System Or Frame Of Reference?
Advantages of studying the collision process of the centre of mass system or frame of reference: When the origin of the reference frame system is a rigidly fixed point to the centre of mass of a system of particles then this type of frame of reference is known as centre of mass reference frame. No…

What Do You Mean By Direct Or Head-On And Oblique Collisions?
A collision may be direct or head-on and oblique. In a direct collision, the direction of motion of both the colliding particles or bodies is along the line of impact both before and after collision. On the other hand in oblique collision the direction of either or both is not along the line of impact.
