What is inelastic collision????? What is the condition???????

dear dholu , momentam conserved , ke not conserved all the best

An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved.

In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.

The formulae for the velocities after a one-dimensional collision are:

where

v_a is the final velocity of the first object after impact

v_b is the final velocity of the second object after impact

u_a is the initial velocity of the first object before impact

u_b is the initial velocity of the second object before impact

m_a is the mass of the first object

m_b is the mass of the second object

C_R is the coefficient of restitution; if it is 1 we have an elastic collision; if it is 0 we have a perfectly inelastic collision, see below.

In a center of momentum frame the formulas reduce to:

v_a = − C_Ru_a

v_b = − C_Ru_b

For two- and three-dimensional collisions the velocities in these formulas are the components perpendicular to the tangent line/plane at the point of contact.
