Inelastic Collision Formula
We can only use momentum conservation as kinetic energy is not conserved. Since they stick together after collision, they move with one final velocity.
m1v1 + m2v2 = (m1 + m2)v
From this we can find the value of final velocity
v = (m1v1 + m2v2)/m1+m2
For kinetic energy, [K.E. = 1/2 mv2]
1/2(m1v12 + m2v22) > 1/2(m1 + m2)v2
Inelastic Collision
Inelastic Collision is a type of collision where momentum is conserved, but kinetic energy is not. In such collisions, the colliding objects stick together, and some kinetic energy is transformed into other forms like vibrational energy or heat. This results in a loss of kinetic energy, which may transform into heat, sound, or deformation.
In this article, we will discuss all details related to inelastic collision such as definition, its types, examples, etc.
