Tutorial

Physical Science: Motion Forces and Basic Science

Variables and Observation and Inference

Learn all about Independent and Dependent Variables, Constants and Controls, and Observations and Inferences on this powerpoint.

Dimensional Analysis

Learn how to complete dimensional analysis problems through this video.

Difference between Dimensional Analysis and Conversion Factor

Conversion factor is switching systems. Such as, miles to kilometers.  But dimensional analysis is switching units, such as centimeters to meters.

Velocity, Area and Density of an Object

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

Definitions of Speed and Velocity

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

Velocity
