Velocity and Acceleration

Speed (m/s) = Distance/time  

Acceleration (m/s^2)= Change in Velocity/Time Taken

Distance/Time Graphs

  • A curve upwards = acceleration
  • A curve downwards = decceleration
  • Straight line diagonal going up = constant speed
  • Straight line diagonal going down = constant speed in other direction
  • Straight line = stopped

Velocity/Time Graph

  • Diagonal line upwards = acceleration
  • Diagonal line downwards = deceleration
  • A curve upwards = increasing acceleration
  • Straight line = steady speed
