scalar and vector

• What should you be able to describe by the end of the video?

  Scalar and vector quantities with examples
• What is the definition of scalar quantities?

  They have magnitude only, no direction
• What does the term 'magnitude' refer to?

  It means size
• Why does distance not indicate direction?

  Because it is a scalar quantity
• If you travel 800 meters, what does that represent?

  Distance
• What is the difference between distance and displacement?

  Displacement includes direction, distance does not
• How is displacement defined?

  Distance in a specific direction
• If you travel 800 meters and your displacement is 500 meters due west, what does this indicate?

  Direction of your journey
• How can vectors be represented visually?

  Using an arrow
• What does the length of an arrow represent in vector representation?

  The magnitude of the vector
• What does the direction of an arrow represent in vector representation?

  The direction of the vector
• What is the significance of scalar and vector quantities in physics?

  • Scalars have magnitude only
  • Vectors have both magnitude and direction
