This document discusses tools and units for measuring various physical properties including volume, mass, length, force, temperature, time, area, and density. It lists common tools used to measure each property and their standard metric units. For example, a graduated cylinder or meter stick can measure volume in liters (L) or cubic units, and a triple beam balance measures mass in grams (g). The document also introduces the International System of Units (SI) as the global standard for measurement and explains formulas and units for calculating derived quantities like area, volume, and density.

1. Notes
Tools and Measurement

2. Tools
• Volume – the amount of space something occupies
– Graduated Cylinder, meter stick
– Units: L (liquid), cubed (solid)
• Mass – The amount of matter that something is made of
– triple beam balance
– Units: g (gram)
• Length – Measure of distance from one point to another
– meter stick
– Unit: m (meter)
• Force – spring scale
– Units: N (Newton)

3. • Temperature – The measure of how hot
or cold something specifically: the
average kinetic energy of the objects
particles
– thermometer
– Units: K (Kelvin) we use °C (Celsius)
• Time – stopwatch
– Units: sec (seconds)

4. SI – International System
• SI: International system (metric) – used
globally as a standard of measurement
and units so that info can be shared
accurately
• Based on 10, making conversion of units
easier
• We do not measure in standard –
EVER!!

5. Area
• Measure of the surface of an object
• Formula: A=lxw
• all answers must be squared units
• m2
, cm2
, km2

6. Volume
• Formula: V=lxwxh for a solid that you can
physically measure
• Units: cubed (for a solid) m3
,cm3
• OR: water displacement, object is placed in
water and the ending value is subtracted starting
value
• Measured by displacement Formula V = V2 – V1
– Units: mL (mL is never cubed)
• 1 mL=1cm3
• Official units = L – liter

7. Density
• Amount of matter in a given volume
Formula: D=m/v
• Units:
• measured with water displacement – g/mL
• Physically measured (solid) – g/cm3
• Density can not be measured directly, you
must know (find) the mass and the volume
to calculate
