Physics P2 1.1 Distance-time graphs. 0.0 / 5 ? PhysicsForces and MotionGCSEAQA Created by: Atlanta and JacobCreated on: 22-09-16 19:23 What does the gradient of the line on a distance-time graph represent? An object's speed. 1 of 11 How does the steepness (gradient) of the line on the distance-time graph reflect speed? The steeper the line on a distance-time graph, the greater the speed it represents. 2 of 11 What can a distance-time graph help us to do? We can use a distance-time graph to help us describe the motion of an object. 3 of 11 How does a distance-time graph show the distance of an object? It shows the distance of an object from a starting point (y-axis) against time taken (x-axis). 4 of 11 What is the speed of an object on a distance-time graph? The distance travelled each second. 5 of 11 What happens on the distance-time graph if an object is stationary? The line on a distance-time graph is horizontal. 6 of 11 What happens on a distance-time graph if an object is moving at a constant speed? The line on a distance-time graph is a straight line that slopes upwards. 7 of 11 How can we calculate the speed of an object? Using the equation: speed in meters per second (ms) = distance travelled in metres (m) over time taken in seconds (s) (look up). 8 of 11 What is the SI unit of distance? Metres (m). 9 of 11 What is the speed of a runner who covers 400m in 50s? 8 m/s. 10 of 11 **LOOK UP COMPARING DISTANCE-TIME GRAPHS** ** 11 of 11
