There are four main vectors:

  • Velocity
  • Displacement
  • Force 
  • Acceleration 

If it is a vector, it must have magnitude and direction. If it doesn't have magnitude and direction, it will be a scalor. 

To calculate speed you need to divide distance (m) by time (s). 

Distance-time graphs:

  • If the line slopes - the student is moving. 
  • If the line is horizontal - the student is stationary. 
  • If the line becomes more steep
