Distance and Displacement

• What is motion defined as?

  An object's change in position
• How is distance defined in motion?

  Length of the actual path travelled
• What is the formula for calculating distance?

  d = d₁ + d₂ + d₃
• What does d₁ represent in the distance formula?

  Movement 1
• What is displacement in motion?

  Object's change in position from start to end
• What is the formula for calculating displacement?

  d = df - di
• What does di represent in the displacement formula?

  Initial position
• What does df represent in the displacement formula?

  Final position
• What is the relationship expressed in the equation C² = a² + b²?

  It relates the sides of a right triangle
• What is the value of C when a = 3m S and b = 4m E?

  C = 5m SE
• How do you calculate C using the given movements?

  Use Pythagorean theorem with a and b
• What are the key differences between distance and displacement?

  • Distance: actual path length travelled
  • Displacement: straight line from start to end
• What are the steps to calculate displacement using coordinates?

  1. Identify initial position (di)
  2. Identify final position (df)
  3. Use formula: d = df - di
