SCALARS VS. VECTORS
Types of Measurement
-
TYPES OF MEASUREMENT
• Scalar
• A quantity that has magnitude only
• 15 meters
• Vector
• A quantity that has magnitude and direction
• 20 meters North
• Magnitude means size
-
DISTANCE VS. DISPLACEMENT
• Distance
• The length of the path traveled from one location to another
• Scalar
• Displacement
• Straight line length from start to finish
• Vector
• Fundamental Unit: Meters (m)
-
SPEED VS. VELOCITY
• Speed
• The rate at which distance changes over time
• Scalar
• Velocity
• The rate at which displacement changes over time
• Vector
• Fundamental Unit: Meters per Second (m/s)

ACCELERATION
Speeding up AND Slowing down.
-
ACCELERATION
• Acceleration
• The rate at which velocity changes over time
• Faster – Positive Acceleration
• Slower – Negative Acceleration
• Deceleration
• Vector
• Fundamental Unit: Meters per Second2 ( m/s2 )
