Physics Section 2a 2.0 / 5 based on 1 rating ? PhysicsGCSEAQA Created by: Antonia LoizouCreated on: 23-02-13 16:56 For any given object it will have the same value anywhere in the universe. Mass 1 of 23 It is caused by the pull of gravitational force. Weight 2 of 23 Weight is a force, what is it measured in? Newtons 3 of 23 Mass is not a force, what is it measured in? kilograms 4 of 23 If an object is stationary it means that all the forces are... balanced 5 of 23 In most real situations at least how many forces are acting on an object along any direction? two 6 of 23 What is the overall force acting on an object called? Resultant Force 7 of 23 If the resultant force on a stationary object is zero, what will the object remain? Stationary 8 of 23 If there is no resultant force on a moving object, what happens? Moves at th same velocity 9 of 23 If there is a non-zero resultant force, what happens to the object? It accelerates in the direction of the force 10 of 23 In what direction does friction always act to movement? Opposite 11 of 23 When an object moves through a distance what is done? Work is done and energy is transferred 12 of 23 Work done= Force x Distance 13 of 23 What is work done measured in? Joules 14 of 23 Gravitational potential energy= Mass x g x height 15 of 23 Kinetic Energy= 1/2 x mass x velocity (squared) 16 of 23 What is kinetic energy transferred? Work Done 17 of 23 When work is done to an elastic object, what is it stored as? Elastic Potential Energy 18 of 23 What is the extension of an elastic object directly proportional to? Force 19 of 23 What happens when the force applied to an elastic object is greater than it's limit of proportionality? It will be permanently stretched 20 of 23 What is power measured in? Watts 21 of 23 Momentum= Mass x Velocity 22 of 23 Momentum Before= Momentum After 23 of 23
