• Velocity

  The speed plus the direction the object is going
• Velocity

  • A car is going 50 km/h north east
• Acceleration

  Any process where the velocity changes. it is speeding up or down
• Acceleration

  v=final velocity, u=initial velocity
• Positive acceleration

  Speeding up
• Negative acceleration

  Slowing down
• Acceleration of 0


  Staying at a constant speed
• Acceleration due to gravity

  A falling object accelerates towards Earth because of gravity. It will speed up as it falls.
