Elasticity is the ratio of the % change in quantity to the % change in price. So if the two are identical, than it is said to be unitary elastic. If quantity changes more than price, then it is said to be elastic. If the quantity changes less than price, then it is said to be inelastic.
There are two types of collisions that occur: elastic and inelastic. Elastic collisions are when the objects are not permanently deformed and heat is not generated from the collision. Inelastic collisions are when the objects stick together or become permanently deformed. Perfect elastic collisions are rare because usually some heat is generated during a collision.
