Physical Science

Open Ended

What is distance?

Distance

Scalar: Only magnitude no direction

• Distance is a scalar quantity

• Distance is the total path travelled over the course of a journey

Multiple Choice

 Amy runs 2 miles south, then turns around and runs 3 miles north. What is her distance travelled?

• 5 miles
• 1 mile 
• 5 miles south

• 1 mile north 

Displacement

Vector: A quantity with magnitude AND direction

• No direction = NOT a vector

• Displacement is a vector

• Displacement is the difference between the initial and the final position

Draw
