1. The problem statement, all variables and given/known data This is a rather conceptual question, but is there a difference between elasticity and young's modulus? I know that the young's modulus can also be stated as the modulus of elasticity, but is it incorrect to say that a substance with a higher young's modulus has a low elasticity? Or should it be that a substance with a very high young's modulus has high elasticity? Are they merely synonyms? 2. Relevant equations Young's modulus = stress/strain 3. The attempt at a solution I am assuming that a high young's modulus equates to lower elasticity.
