Presentation Transcript

Metric system prefixes and base units
Metric System Prefixes and Base Units

  • Base Units:

    • Meter- length

    • Gram – mass

    • Liter – volume

  • Prefixes:

    • Kilo, Hecto, Deka, Base Unit, Deci, Centi, Milli


Length
Length

Distance of an object

Units: Meter


Measurement

MASS!

(amount of matter in an object)

Amount of stuff in stuff


Measurement

-_Weight_-

How hard gravity

Pulls on the mass


There is a difference between
There is a difference between….

  • Mass = the amount of matter in and object.

    Units = Grams or Kilograms

  • Weight = how much gravity pulls on your mass. Units = Newtons

Measurement

VOLUME <3http://www.youtube.com/watch?NR=1&v=1whMAIGNq7E&feature=endscreen

The amount of space

an object takes up.

Units = cm3 or ml


How to find volume
How to find volume?http://www.youtube.com/watch?NR=1&v=1whMAIGNq7E&feature=endscreen

  • Measure Length x width x height = cm3

    or

  • Water displacement = ml


Density
DENSITY http://www.youtube.com/watch?NR=1&v=1whMAIGNq7E&feature=endscreen

How tightly packed an object is.


Measurement

  • Density = Mass divided by volumehttp://www.youtube.com/watch?NR=1&v=1whMAIGNq7E&feature=endscreen

  • D = M or

    V

    =

    Units g/ml or g/cm3

    if you used water if you used l x w x h
