3
Speed (REVIEW)

• Rate at which object moves
• Speed distance time
• Constant, changing, average
• Shown w/distance-time graph

4
Velocity (REVIEW)

• Speed and direction
• Shown with an arrow
• Longer arrow faster speed

5
Acceleration

• Speeding up
• Slowing down
• Changing direction
• In other words
• Change in velocity

6
Acceleration, cont.

• Like velocity, shown with arrow
• ? velocity, accel. is same direction.
• ? velocity, accel. is in the opposite direction.
• Turning, accel. is toward inside of turn.

HW Hand analogy, ISN p. 18

• Trace your hand at the top. In the palm write
  acceleration and draw a picture representing
  accel.
• On each of the 4 fingers, write a related term
  and draw a picture (outside the point of the
  finger)
• On the thumb, write a related but opposite term.
• Below the hand, describe the following in 3
  paragraphs
• 1. Explain the picture in the palm.
• 2. Explain how each of the pictures/terms on the
  digits relates to the term on the palm.
• 3. Explain how the term on the thumb is related
  and yet opposed to the term on the palm.
