Physics Test On Modulus Of Elasticity! Trivia Quiz

Elasticity, according to our physics class, is the ability of an item to revert to its size after it has been stretched. Hooke`s law forms the basis of measuring the elasticity of an item. Below is a Physics test on the modulus of elasticity and it is designed to help you test out just how much you know. All the best!
