elasticity 0.0 / 5 ? PhysicsForces and MotionIGCSEAQA Created by: monicaburman12Created on: 22-02-17 20:40 What does an object need to do to be classed as elastic? If it is elastic it regains its original shape when the forces deforming it are removed 1 of 7 What is extension? The difference between the length of the spring and its original shape 2 of 7 What happens when and elastic object is stretched? Work is done, stored as elastic potential energy in the object, when stretching forced is removed this stored energy is released 3 of 7 What does Hookes law state? The extention is directly proportional to the force applied, provided the limit of proportionality has not been exceeded. 4 of 7 What happens if the force applied to stretch an object is too great? The graph starts to curve because the limit of proportionality has been exceeded 5 of 7 What is the spring constant of a spring? The force per unit extension needed to stretch it 6 of 7 The stiffer the spring.... The greater the spring constant 7 of 7
