Examine the figure, if you were standing under the tree, which object would appear to be moving?

• the tree

• the airplane

• the boy

• the building

A passenger in the rear seat of a car moving at a steady speed is at rest relative to

• the side of the road

• a pedestrian on the corner ahead

• the front seat of the car

• the wheels of the car

Which distance can be most accurately measured with a ruler?

• the length of a river

• the width of a book

• the distance between 2 cities

• the size of an object under a microscope

One kilometer equals 1000 meters. What does the prefix Kilo- mean?

• 1

A person walks 1 mile every day for exercise, leaving their porch at 9:00am, and returning to her front porch at 9:25am. What is the total displacement of their daily walk?

• 1 mile

• 0

• 25 minutes

• none of the above

A person drives north 6 blocks, then turns west, and drives 6 blocks. The driver then turns south and drives 6 blocks. How could the driver have made the distance shorter while maintaining the same displacement?

• by driving 6 blocks west from the starting point.

• by driving north 4 blocks and west 7 blocks

• by driving south 6 blocks from the starting point

• by driving back to the starting point by the same route

Displacement vectors of 4km south, 2km north, 5km south, and 5km north combine to a total displacement of

• 16 km north

• 11km west

• 6km south

• 2km south

Speed is the ratio of the distance an object moves to

• the amount of time needed to travel the distance.

• the direction the object moves.

• the displacement of the object.

• the motion of the object.
