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
