Initial velocity and final velocity 1 of 9 What is the value of g? 9.8 2 of 9 What must the resultant force of a particle equal in order for it to be in equilibrium? 0 3 of 9 What added force is present when a particle is at rest on a rough surface? Friction 4 of 9 What term is defined by 'the shortest route between two points.' (It is a vector quantity so a distance and direction are needed)? Displacement 5 of 9 On a displacement - time graph, what does the change in displacement/time calculate? velocity 6 of 9 What does a horizontal line on a (t, x) graph indicate? The displacement is not changing i.e. the object is stationary 7 of 9 On a velocity - time graph, what does the change in velocity/time calculate? acceleration 8 of 9 In Newton's second law, what is the resultant force equal to? mass by acceleration 9 of 9
