Additional physics-Velocity and distance time graphs 0.0 / 5 ? SciencePhysicsGCSEAQA Created by: nimrahali12Created on: 20-09-16 19:32 What is speed and velocity? how fast your going 1 of 15 What is this measured in? m/s 2 of 15 What is the difference between speed and velocity? Speed is how fast your going with no regard of direction and velocity is with what direction your going 3 of 15 Whats the formula for speed? distance divide by time =speed 4 of 15 what doe the gradient of distance time graph tell you? How fast your object is travelling 5 of 15 Why is this? Because the gradient is the change in the distance (vertical axis)divided by the change in time (horizontal axis) 6 of 15 Gradient equals? speed 7 of 15 What do flat sections on distance time graph mean? stationery-its stopped 8 of 15 Straight uphill or downhill sections mean? travelling at a steady speed 9 of 15 The steeper the graph? the faster its going 10 of 15 Downhill sections mean? its going back towards its starting point 11 of 15 Curves represent? acceleration or deceleration 12 of 15 The steepening curve means? its speeding up and increases gradient on the graph 13 of 15 Levelling off curve means? Its slowly slowing down (decreasing gradient) 14 of 15 How do you calculate speed from graph? Speed=gradient=vertical divided by horizontal 15 of 15
