• Three types of graph that can represent motion are?displacement-time?graphs,?velocity-time?graphs and?acceleration-time?graphs
• On a?displacement-time graph…
  • slope?equals?velocity
  • the?y-intercept?equals the?initial displacement
  • a?straight(diagonal) line represents a?constant?velocity
  • a?curved?line represents an?acceleration
  • a?positive?slope?represents motion in the?positive?direction
  • a?negative?slope?represents motion in the?negative?direction
  • a?zero?slope (horizontal line) represents a state of?rest
  • the area under the curve is meaningless

• On a?velocity-time graph…
  • slope?equals?acceleration
  • the?y-intercept?equals the?initial velocity
  • a?straight?line represents?uniform?acceleration
  • a?curved?line represents?non-uniform acceleration
  • a?positive?slope represents an?increase?in?velocity?in the?positive?direction
  • a?negative?slope represents an?increase?in?velocity?in the?negative?direction
  • a?zero?slope (horizontal line) represents motion with?constant?velocity
  • the?area?under the curve equals the?displacement?or?distance?travelled

• On an?acceleration-time graph…
  • slope is meaningless
  • the y-intercept equals the initial acceleration
  • a zero slope (horizontal line) represents an object undergoing constant acceleration
  • the area under the curve equals the change in velocity
