FORCES IN ACTION 0.0 / 5 ? PhysicsForcesGCSEAQA Created by: TarajenCreated on: 03-10-17 18:06 When is work done on an object? When a force causes an object to move. 1 of 9 What is the definition of elastically deformed? If the object returns to its origianl shape after the forces are removed. 2 of 9 What is the definition of inelstically deformed? If the object does not return to its original shape. 3 of 9 Directly proportional The extention of an elastic object is.......to the applied force 4 of 9 force= spring constant x extention 5 of 9 What does the spring constant indicate? how easy it is to stretch or compress a spring - the higher the spring constant the stiffer the spring. 6 of 9 What is the moment of a force? When a force causes an object to rotate about a pivot point it is the turning effect. 7 of 9 Moment of a force? force x distance 8 of 9 Name two things leavers and gears can be used to do.. Transmit the rotationl effects of forces. Magnify either the size of the applied force or the distance the force moves over. 9 of 9
