Learn how to complete dimensional analysis problems through this video.
Conversion factor is switching systems. Such as, miles to kilometers. But dimensional analysis is switching units, such as centimeters to meters.
Area: length x width (cm3)
cm3--centimeters cubed
Volume: length x width x height (cm3 or mL)
cm3--centimeters cubed
Density: mass/volume (mass dived by volume) -- (g/mL) -grams per milliliter
Speed:
-how fast something is moving
-the rate of change of position
**always positive
Velocity:
-rate of chage of position in a specific direction
**can be positive or negative
--negative velocity means something is traveling in the opposite direction
