You run home from school during lunch because you forgot to pack one. You travel 2 km north and then realize that you forgot your key so you head back to school to get it. Then you travel the 3 km back to your house, eat lunch, and make it back to school in time for 4^th period. What was your total distance traveled? What was your displacement?

• Distance: 10 km, Displacement 0 km

• Distance 8 km, Displacement 0 km

• Distance 10 km, Displacement 3 km N

• Distance 8 km, Displacement 8 km N

You have spun around in a circle and are very dizzy. You are trying to reach your locker. You travel 2 meters north, then 1.5 meters west, then another 4 meters north before reaching your locker. What was your total distance traveled? What was your displacement?

• Distance 6.2 m, Displacement 0

• Distance 6m, Displacement 6.2 m NW

• Distance 7.5 m, Displacement 1.5 W

• Distance 7.5 m, Displacement 6.2 m NW

A whale swims due east for a distance of 6.9 km, turns around and goes due west for 1.8 km, and finally turns around again and heads 3.7 km due east. What is the total distance traveled by the whale? What is the displacement of the whale?

A student lives 3 km North of the school. They start to walk to school for the day and get 2/3 of the way when they realize they forgot their Physics homework (a tragedy). So they walk back to get it and then make it all the way back to school. What distance did they travel and what was their displacement?

• Distance 7 m, Displacement 3 m S

• Distance 7 m, Displacement 0

• Distance 9 m, Displacement 0

• Distance 9 m, Displacement 3 m S
