Acceleration

• Define Acceleration.

  The change in velocity in a certain amount of time (how quickly something speeds up or slows down)
• Is Acceleration a vector or scalar quantity?

  Vector
• What does negative acceleration represent?

  Deceleration
• Why do we calculate acceleration as an average?

  Because acceleration can vary over the time something accelerates
• What is the equation for acceleration that does NOT include distance?

  Acceleration (m/s) = change in velocity (m/s) / time (s)
• What is the equation for acceleration that includes distance?

  2 x Acceleration (m/s) x distance (m) = Final velocity (m/s) - Initial (starting) velocity (m/s)
• What is always the initial velocity of an object that is being dropped?

  0 (because the object was stationary before it was dropped)
• What is the acceleration of anything that gets dropped on earth? - hint the answer links to gravity

  9.8 m/s because of the force of gravity
