21
Q

Density is equal to…

A

Mass (or weight) divided by volume

22
Q

Define force and give the formula

A

Created by acceleration; F=ma

23
Q

Give formula if weight is a force

A

Fw=mass X acceleration of gravity

24
Acceleration of gravity is equal to...
9.8 m/s^2
25
Mathematical basis for metric system? Official name?
Base 10; Standard International
26
Why is SI the system used in science?
Base 10, easy conversions
27
Most recent definition of a standard meter?
Distance light travels in a vacuum over a certain amount of time
28
Only fundamental quantity measured by comparison of a physical object? Why?
Kilogram, still the most accurate
29
Original standard of a second? Updated standard?
1/86400 of a day; # of vibrations of cesium -133 atom
30
SI includes what standards?
Same as metric but uses Kelvin for temp.
31
Metric system uses what standards?
Has a decimal basis (base 10) | Temp is measured in Celsius
32
Name the seven fundamental Units
1. Length - meters 2. Mass - kilogram 3. Time - second 4. Temp. - kelvin 5. Electric current - Ampere 6. Amount of substance - mole 7. Luminous intensity - Candela
33
Accuracy
Closeness of a measurement to actual value
34
Precision
Ability to repeat measurement with "same" result
35
Specific Gravity is the
Density of an object divided by density of water
36
Density of water is equal to
1 g/cm^3
37
1 dm^3 is equal to what?
1 Liter
38
1 Liter is equal to what?
1000 mL
39
1 cm^3 is equal to?
1 mL
40

Gravity
41
What is the SI unit for force or weight?
Newton
42
What is the formula for weight?
Mass (kg) X 9.8 m/s^2
