  1. Compare average speed to instantaneous speed
    Average Speed is the total distance travelled divided by the total time to travel the distance.

    Instantaneous Speed is speed of an object at a certain point of time or at one instant of time
  2. Compare speed to velocity
    (scalar vs. vector)
    • Speed = D/T (scalar)
    • Velocity = speed in a certain direction (vector)
  3. Compare Distance to Displacement
    (scalar
    vs vector)
    Distance = total length covered from beginning to end (scalar)

    Displacement = length from the starting point to the ending point in a straight line and direction (vector)
  4. List the 3 ways to cause acceleration
    • 1. speed up
    • 2. chenge direction
    • 3. slowing down
