Question

what does it mean to say that for completely inelastic collisions, the deformations may not be relieved and the particles move together ? what is the value of final kinetic energy ? here what does the word deformations mean ?

Answer 1

• During perfectly inelastic collision, the bodies undergoing collision will combine and move as a whole, that is, they stick to each other and move.
• The final kinetic energy is equal to the difference between Total kinetic energy before collision and loss of kinetic energy during the collision.
• Deformation means change in the size/shape of the bodies.
