PhysicsForces and MotionGCSEAQA Created by: LSmithCreated on: 26-03-14 15:05 An elastic object such as a spring stores __________ when stretched or squashed Elastic potential energy 1 of 12 The extension of an elastic object is _____________ to the force applied Directly proportional 2 of 12 _____________ on an elastic object when its shape changes Work is done 3 of 12 When an elastic object - such as a spring - is stretched, the increased length is called its... Extension 4 of 12 The extension of an elastic object is _____________ to the force applied to it Directly proportional 5 of 12 F = k × e F=? F = Force (Newtons) 6 of 12 F = k × e k=? k = spring constant (N/m) 7 of 12 F = k × e e=? e = extension (m) 8 of 12 When will this equation not work? If the elastic limit (limit of proportionality) is exceeded 9 of 12 What will happen if a spring is stretched too much? It will not return to its original shape once the load is removed 10 of 12 How do you find the spring constant? Work out the gradient 11 of 12 How do you find the extension? The new length minus the original length 12 of 12
