I. Frame of Reference

• 1. The object or point from which movement is
  determined.
• 2. The most common frame of reference is the
  Earth.
• 3. The frame of reference is assumed to be
  stationary.

II. Motion

• 1. A change in position in a certain amount of
  time, which is relative to a given frame of
  reference.

• 2. Units
• Km/h Kilometers per hour
• m/s meters per second
• Speed Distance
• Time

III. Speed

• 1. On a distance time graph, the slope of the
  line indicates the speed the steeper the
  slope, the faster the speed.
• 2. Constant Speed Speed that does not change.
  If slope is completely straight then the speed
  must be constant.
• 3. Average Speed When the speed of a moving
  object is not always constant.
• Average Speed Total Distance
• Total Time

IV. Velocity Speed in a given direction.

• 1. Velocities that have the same directions
  combine by addition.
• Example Rowing downstream
• 2. Velocities that have opposite directions
  combine by subtraction.
• Example Rowing upstream
