2. Graph Interpretation
“Directly proportional”
“Inversely proportional”

3. slope = rise / run
slope = 6 m/s / 4 s
slope = 1.5 m/s/s
(or slope = 1.5 m/s2)

4. English to Metric Conversion problem
Convert your weight to metric weight where 1 kg = 2.2 lb.
130 lb 1 kg = 59 kg
2.2 lb

5. Unit analysis Conversions Weight: 2.2 lb = 1kg Length: 1.0 in = 2.54cm
5280 ft = 1 mile
0.625 mile = 1 km
Volume: 1.06 qt = 1.0 L
30. mi/gal = ? km/L

6. Percent Error Va is the accepted value and Vo is the observed value Va
% Error = / Vo - Va/ x 100 Va
