A collision is said to have taken place if two bodies interact with each other and undergo a change in momentum and / or kinetic energy.
Types of Collision
(a) Perfectly Elastic Collision
A collision is said to be perfectly elastic if law of conservation of momentum and that of kinetic energy hold good during the collision.
(b) Inelastic Collision
A collision is said to be inelastic if law of conservation of momentum holds good during collision while that of kinetic energy is not.

There are two general types of collisions in physics: elastic and inelastic.
An inelastic collisions occurs when two objects collide and do not bounce away from each other.
An elastic collision occurs when the two objects "bounce" apart when they collide. Two rubber balls are a good example.

Given AP = a , T₂ , T₃....., ,b
Sum of Given A.P. =[ a+ (a+d)+(a+2d)+(a+3d)+..+(a+nd)]
A.P. = [(b-nd)+...+(b-3d)+(b-2d)+(b-d)+b]
By Adding both A.P. we get 2(A.P.) = na+nb + 0d
A.P. = n(a+b)/2
Sum of terms = ½n(a+b)
