velocity

• Velocity


  The speed of an object in a given direction
• Velocity is a vector quantity
• Speed


  Does not give any idea of the direction of the journey
• Speed is a scalar quantity
• Calculating velocity


  1. Speed = Distance / Time

  2. Also state the direction
• If an object moves at a constant speed in a circle, its velocity is constantly changing
• This also applies to an object traveling around part of a circle, e.g. moving around a corner
