Distance-Time Graphs

• Distance-Time Graphs


  Graphs that contain information about the distance travelled by an object over time
• Distance-time graphs can look complicated, but they contain a lot of information
• Distance-time graphs


  • Can show journeys of objects moving in a straight line
  • The shape of the graph shows how the object is moving
• Interpreting distance-time graphs


  1. Gradient = speed

  2. Flat sections = object is stationary

  3. Straight uphill sections = object travelling at steady speed

  4. Curves = acceleration or deceleration

  5. Steepening curve = object speeding up

  6. Levelling off curve = object slowing down

  7. To find speed at a point, find gradient of tangent to curve at that point
• Speed = distance / time
