Metric System |
-SI system: "system international" -useful to have one measurement system for all of science |
|
|
What can be measured? |
1) length - meter(m) 2) mass - gram(g) 3)volume - liters(L) 4)temperature - Celsius/Kelvin 5)time - second |
|
|
Volume |
-the amount of space an object takes up -regular objects (length x width x height) -irregular objects (water displacement) |
|
|
Base Units |
grams(g) - meters(m) - liters(L) |
|
|
Dimensional Analysis |
-used to convert units into relevant units |
|
|
Conversion Factor |
-a ratio that's written as a fraction that relates 2 units with the same relative amount Ex. 12in/1ft |
|
|
Density |
-how much of a substance exists in a specific space -formula - mass/volume=density -it's unique to every substance |
|
|
Percent Error |
-measures how accurate your found data is -formula - your value-known value ----------------------------------- x 100 known value |
|
|
Water Density |
-density of water - 1.0 g/mL less than - floats more than - sinks |
|
|
Precision |
-all measured values are close to each other but not necessarily to the target value |
|
|
Accuracy |
-all measured values are close to and hit the target value |
