What Do You Mean By Inelastic Collision?
—
by
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…

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 Is A Collision?
—
by
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…

Calculate The Change In The Values Of Energy And Angular Momentum When A Two Body System Interacting Through Gravitational Force Is Reduced To An Equivalent One Body Problem.
—
by
Change In Total Energy: Let us consider a two body system of masses and having position position vectors and respectively with respect to the origin O. The distance between and is , or, . Now the gravitational force of attraction between the two masses is where, G is the gravitational constant. If we take magnitude…

Discuss The Motion Of the Reduced Mass Under The Influence Of Inverse Square Force.
—
by
Motion of reduced mass under inverse square force: Let, gravitational force is taken as an example of inverse square force. Now the force of attraction due to the gravitational force between the two mass points and is given by where G is the gravitational constant. If be the reduced mass of the system of these…

Define Reduced Mass.
—
by
Reduced mass: When there is no external force acting on a system of two particles and the only forces are those of mutual interaction, then the system behaves as a single particle of mass. Let us consider a system of two particles and having position vector and respectively with respect to the origin O as…
