Scalar and vector quantities

• What are scalar quantities?

  Quantities with magnitude only
• Why do scalar quantities not have a direction?

  They only represent size or magnitude
• If you travel 800 meters, what does that represent?

  A scalar quantity: distance
• How does distance differ from displacement?

  Distance has no direction; displacement does
• What is the displacement if you travel 800 meters due west?

  500 meters due west
• 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
• Why is displacement considered a vector quantity?

  It has both magnitude and direction
• How can you represent a vector quantity visually?

  Using an arrow
• What is the significance of stating both magnitude and direction in displacement?

  It provides complete information about the vector
• What is the key point about scalar quantities?

  They have magnitude only
• How does the concept of direction apply to scalar quantities?

  Scalar quantities do not include direction
• If you state a distance of 800 meters, what information is missing?

  The direction of travel
• How do scalar and vector quantities relate to physics measurements?

  They represent different types of physical properties
• What is the relationship between distance and displacement in a journey?

  Distance is total travel; displacement is net change
• What is the direction of the displacement if you travel 500 meters due west?

  Due west
• Why is it important to understand scalar and vector quantities in physics?

  They are fundamental to understanding motion and forces
• How can the concept of magnitude be applied to both scalar and vector quantities?

  Magnitude indicates size in both types
