Question
Do perfectly elastic and perfectly inelastic collisions exist? 2 marksYes. All collisions are perfectly elastic or perfectly inelastic No. All collisions are a mix of the two. Both A and B Only B
Solution
Only B. In reality, all collisions are a mix of the two. Perfectly elastic and perfectly inelastic collisions are idealized situations. In a perfectly elastic collision, kinetic energy is conserved, while in a perfectly inelastic collision, the two objects stick together and move as one after the collision. However, in real-world collisions, some kinetic energy is always converted into other forms of energy, such as heat or sound, making the collision inelastic to some degree.
