Elastic limit definition gcse. Mar 28, 2025 · Force, extension and spring constant are used to define Hooke's Law. The child and pogo stick are not moving. 3. If you stretch an object too much it can pass its 'elastic limit' (also known as the 'limit of proportionality'). 5. You need to understand each of these three effects, and give examples of forces causing each. GCSE AQA Synergy Energy changes - AQA Synergy Elastic deformation Energy is a key principle in physics. This lesson covers GCSE Physics 4. Elastic and plastic, elastically deformed and inelastically deformed. Hooke's law states that the extension of a material is directly proportional to the applied force, meaning that if the force doubles, the extension doubles as well. When an elastic object is stretched beyond its elastic It is the material’s highest limit before the material’s plastic deformation can occur. Examples of elastic objects: Metal springs, elastic bands (when stretched by a small amount), foam mattresses. See full list on shalom-education. In the context of GCSE Physics, this concept is highlighted when discussing the behaviour of materials like springs or rubber bands under stress. Elastic and Inelastic Deformation Elastically Deformed An object is said to be elastically deformed when it is stretched or compressed and returns to its original shape once the force is removed. Aug 12, 2023 · The elastic limit is the maximum stress or force that a material can withstand while still being able to return to its original shape once the force is removed. Calculating extension The limit of proportionality Hooke’s Law . At this point what will happen to the object? Learn about and revise shape-changing forces, elasticity and the energy stored in springs with GCSE Bitesize Combined Science. Forces cause changes and energy calculations allow us to measure how much change can happen Forces and Elasticity (GCSE Physics) Forces and Elasticity Forces Acting On Objects Forces can cause stretching, bending or compression of an object. The spring constant of the spring on the pogo stick is 4900 N/m. The elastic limit of a material is the furthest point it can be stretched or deformed while being able to return to its previous shape. This type of deformation occurs within Forces - 5. This section explains forces and elasticity covering, elastic and inelastic deformation, extension of spring and forces and extension’s linear relationship. The figure below shows the forces acting on a child who is balancing on a pogo stick. The extension of an elastic object, is directly proportional to the force applied, provided that the limit of proportionality is not exceeded. Elasticity worksheets, questions and revision for GCSE Combined Science and Physics. This law is also known as Hooke’s Law. Lets break down the definition into parts: Extension, this is the increase in length. All the revision you need in one place. The lesson covers: Stretching, bending, compressing. Mar 4, 2025 · Complete No-Prep lesson with exam questions, tasks and answers on Forces and Elasticity (Hooke’s Law) for AQA GCSE (9-1) Science / Physics. If the applied force exceeds the elastic limit, the material will undergo inelastic deformation, and Hooke's Law will no longer apply. 3 / Combined Science 6. Once the stress or force is removed from the material, the material comes back to its original shape. Jun 10, 2025 · Elastic deformation refers to the temporary change in shape or size of a material when a force is applied, and importantly, it returns to its original form once the force is removed. 3 Forces and Elasticity (GCSE Physics AQA) Forces and Elasticity Forces Acting On Objects Forces can cause stretching, bending or compression of an object. Where F F is the force applied to the spring, k k is the spring constant, and e e is the extension. Jun 10, 2025 · Hooke’s Law is a fundamental principle in physics which states that, for elastic materials within their limit of elasticity, the extension or compression of a spring is directly proportional to the force applied to it. Mar 28, 2025 · Revision notes on Hooke's Law for the AQA GCSE Combined Science: Trilogy syllabus, written by the Science experts at Save My Exams. com The limit of proportionality is the point where the object no longer deforms elastically, and starts to deform inelastically. Elastic deformation occurs as long as the material is below its Mar 5, 2025 · What is the limit of proportionality? In GCSE Physics, the limit of proportionality refers to the point on a force-extension graph where a material stops obeying Hooke's law. zrswm posrmd rerz lsupgs gxdo nriqga kdngs bnxjc nrh unxsh
