Physics P2: Velocity & Distance Time Graphs 5.0 / 5 based on 4 ratings ? PhysicsForces and MotionGCSEAQA Created by: jamesmarkwallisCreated on: 03-05-15 13:52 What is velocity? Velocity is the speed of something in a given direction 1 of 11 What is speed? The rate at which something moves 2 of 11 What is speed to? (Calculation for speed) Speed = Distance/Time 3 of 11 In a distance time graph, what is the gradient showing? Speed 4 of 11 In a distance time graph, if the line is flat and horizontal, what does it mean? The object is stationary 5 of 11 In a distance time graph, if the line is going straight up or down, what does it mean? The object is travelling at a steady speed (Up= Steady acceleration, Down = Steady acceleration) 6 of 11 True or false. When the graph is not steep, it means the speed is fast False, the steeper the graph the faster the speed is! 7 of 11 What do curves represent? Acceleration or deceleration 8 of 11 How do you calculate speed from a distance time graph? Speed = gradient = vertical/horizontal 9 of 11 What is accelaration? Acclaration is how quickly the velocity is changing, or ' the rate of change of velocity per unit of time' 10 of 11 What is the formula for accelaration? Change in velocity/time taken. 11 of 11
