acceleration

• Acceleration


  The change in velocity of an object over a given time
• Calculating acceleration


  Acceleration (m/s^2) = Change in velocity (m/s) / Time (s)
• Deceleration


  Negative acceleration, when an object is slowing down
• Velocity-time graph


  • Horizontal line = constant velocity
  • Upward sloping line = acceleration
  • Downward sloping line = deceleration
• Calculating acceleration from velocity-time graph

  Acceleration = (Final velocity - Initial velocity) / Time
• Displacement


  The total distance traveled in a specific direction
• Calculating displacement from velocity-time graph


  Divide graph into shapes (triangles, rectangles)

  Calculate area of each shape

  Add up total area to get displacement
