Motion

• Distance

  How far an object moves
• Gradient of the line means the

  Speed of the object
• Displacement

  How far an object moves from a starting point
• Speed


  Rate of change of distance (traveled per unit time)
• Steepness of the line

  Faster the object is moving
• Velocity

  Speed in a particular direction
• Acceleration


  Rate of change of velocity (vector)
• Change in velocity is measured in ?

  (m/s²)
• Displacement


  Distance (m)
• Acceleration

  Change in velocity/time taken
• SUVAT equation

  Equation to calculate final velocity
• Velocity-time graph


  Gradient of the line is equal to the acceleration of the object
• Displacement


  Displacement of an object can be calculated from the area under the graph
• Thinking distance 


  Distance travelled while you are thinking about stopping
• Braking distance 


  The time it takes for your vehicle to stop when you apply the brake
