Standing on the Santa Fe High School plaza you observe a bird flying from tree to tree. The place on the plaza that you observe from is your

• frame of reference

• relative motion

• distance

• relative distance from bird

Motion in relation to a frame of reference is called relative motion.

• True

• False

Imagine that you are a passenger in a car.

The best frame of reference you could use to determine how fast the car is moving relative to the ground is_______

• . the people sitting next to you in the backseat

• the driver of the car

• a van traveling in the lane next to your car

• .a sign post on the side of the road

Distance is the length of a path between two points

• FALSE

• TRUE

• Not enough information is given to determine whether or not this is distance.

the SI unit best suited for measuring the length of a room in your home.

• kilometer

• centimeter

• millimeter

• meters

Five blocks south is an an example of displacement

• True

• False

• Neither

Which is NOT magnitude.

• length

• amount

• size

• direction

Compare and contrast distance and displacement.

• Distance is the magnitude of a path between two points, whereas displacement is the direction from a starting point and the length of a straight line from the starting point to the ending point.

• Distance is the speed of a path between two points, whereas Distance is the length of a path between two points, whereas displacement is the direction from a starting point and the length of a straight line from the starting point to the ending point.

• Distance is the length of a path between two points, whereas displacement is the direction from a starting point and the length of a straight line from the starting point to the ending point.

A vector is a quantity that has both ______________ and _________

• speed and velocity

• distance and time

• gravity and free fall

• magnitude and direction
