Position and Motion

Displacement is the difference between your

• reference point and reference direction

• total distance traveled

• starting position and your final position

• average speed

You ride your bike 10 miles East but then head West for 6 miles. What is your displacement?

• 16 miles East

• 4 miles East

• 4 mile West

• 6 miles West

You are in a car that drives away from Beaver Stadium. How would you describe your motion relative to the stadium? To the car?

• Stadium- Not moving; Car- Moving away

• Stadium- Moving toward; Car- Not moving

• Stadium- Moving away; Car- Moving closer

• Stadium- Moving away; Car- Not moving

Suppose you travel 10 miles East on your bike from your house and then 6 miles West. If the reference direction is East, then what is final position relative to your house?

• +4 miles

• -4 miles

• +16 miles

• -6 miles

An object's location or _______________ is the distance from a reference point.

• distance

• position

• acceleration

• displacement

Which line on the graph represents the fastest constant speed?

• A

• B

• C

• They are all moving at the same speed.

How would a distance-time graph appear for an object that is not moving?

• A line that curves upward

• A straight vertical line

• A straight horizontal line

• A line that goes up and to the right

If the reference point is your home and you travel 5 miles to get to Quaker Steak and then come back home, what is the total distance traveled?

• 5 miles

• 10 miles

• 0 miles

• 25 miles

An object that keeps getting faster away from a reference point on a distance-time graph will appear as a line that

• is straight and moves up and to the right.

• is straight and horizontal.

• curves downward (down and to the right).

• curves upward (up and to the right).

How can you tell if an object is getting closer to a reference point using a distance-time graph?

• You cannot tell if an object is getting closer to a reference point.

• The line approaches the y-axis (distance decreases).

• The line approaches the x-axis (distance decreases).

• The line curves upward.
