1. Video:  Speed and Velocity

• Speed: how fast something travels

• Velocity: an object’s SPEED and DIRECTION

            velocity = displacement / time

             v = ∆d/ ∆t

  2. Calculations:  Using a Scientific Formula

Scientific formulas use variables that represent measurements. 

To use a scientific formula, we can plug in measurements for each variable. Context clues and units tell us which numerical values to plug in for each quantity. 

The units used to measure velocity are meters per second (m/s)

The units used to measure distance or displacement are meters (m)

The units used to measure time are seconds (s) 

All formulas for the course are listed on the Physical Science Reference Tables
