  1. Representing Motion Chapter 2

  2. Important Terms Scalar: quantities, such as temperature or distance, that are just numbers without any direction (magnitude) EX: 15 m, $5.50, 98° Vector: quantities, such as position, that have both magnitude and direction EX: 15 m North, - 5 ft, 4 cm down

  3. How far? Distance: a scalar quantity that describes how far an object is from the origin Symbol: “x” or “y” Units: m (meters) Displacement: a change in position having both magnitude and direction; it is equal to the final position minus the starting position Symbol: “Δ x” or “Δ y” Δ (delta) :“change in” Units: m

  4. EX: Joey runs 400 m around the track and finishes exactly where he started. What is Joey’s: • distance traveled? • displacement?

  5. How fast? Speed: distance traveled in a time interval (scalar) Symbol: v Units: m/s (meters per second) Velocity: displacement traveled in a time interval (vector) Symbol: v Units: m/s

  6. Representing Motion
