Measurement Facts Reviewed in Class
- What is common measurement of a: Volume, Mass, Distance?
- Mass is the measurement of how much matter an object contains
- Are mass and weight the same thing?
- What do we use in our lab to Mass object?
- Examine you triple beam balance. What is each beam for?
- What is the least and most mass you can mass on it?
SI Units For: Measurement
Measuring Mass: Mass is the measurement of how much matter an object contains
We use a triple beam balance to measure mass.
Are mass and weight the same thing?
Mass vs. Weight
Weight is a measure of the force of gravity on you
Mass does not change.
An object’s weight will change if you move it from Earth to the moon or to other planets.
Weight = mass x gravity
Gravity = 9.8 m/s2
Mass is measured in kilograms
A smaller unit is also used
Mass is measured using a triple beam balance
The amount of space that occupies matter
Volume is measured in several units
Cubic centimeters (cm3)
For rectangular objects, volume can be found by multiplying the measurements of length, width, and height
Volume = length x width x height
Length is measured in meters
1 kilometer = 1,000 meters
1 centimeter = .01 meters
Length is measured using a meter stick or a ruler
Temperature is measured in degrees Celsius (oC)
Water freezes at 0o Celsius
Boils at 100o Celsius
