Where, Oh, Where? Distance (d) refers to how much ground an object has covered.Distance vs. Displacement
Fifty Meters To The Outhouse? Written By Willi Makit Illustrated by Betty Wont
DISTANCE (d) refers to how much ground an object has covered.
Displacement refers to the LENGTH and DIRECTION of a straight line from the INITIAL position to the FINAL position of an object.
Is distance a scalar or vector? (write this question in your notebook.) a. Scalar b. Vector c. Neither d. Both
Is displacement a scalar or vector? (write this question in your notebook.) a. Scalar b. Vector c. Neither d. Both
displacement = Δd = df – di f = final position i = initial position
1. A physics student walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North. DRAW A DIAGRAM HERE:
1. A physics student walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North. (draw this diagram in your notes)
Distance traveled? a. 6 m b. 12 m c. 0 m d. 4 m
Displacement? a. 6 m b. 12 m c. 0 m d. 4 m
2. On the sketch below, the ship travels from point x past the lighthouse to point z.
1. Draw a dark line representing the DISTANCE the ship travels. 2. Draw a dashed line representing the ship’s DISPLACEMENT. 3. Measure the ship’s distance (cm). 4. Measure the ship’s displacement (cm)
Speed is a scalar quantity: Speed = __Distance__ Time
Velocity is a vector quantity: Velocity = _Displacement_ Time
