200

  • 200: What term means an object’s distance and direction from a reference point? 

Position

200

  • 200: Fill in the blank: A table is 10 m from a statue but 12 m from a fountain. The ______ changes your description. 

Reference point

200

  • 200: Give an example of an object in motion relative to one point but not another. 


  • (Boat moves relative to buoy but not to fishing pole)

200

  • 200: Define displacement.


  • (Difference between starting and ending positions)

200

  • 200: When can an object be in motion relative to one point but not another? 

When the reference point changes

300

  • 300: What is the process of changing position called? 


Motion

300

  • 300: How can position be described in two dimensions? 

  • (Using two reference directions, like north/south and east/west)

300

  • 300: What must change for motion to occur? (The object’s position relative to a reference point)


  • (The object’s position relative to a reference point)

300

  • 300: A baseball player runs 360 ft around the bases. What is the distance traveled? 

360 ft.

300

  • 300: Name one reason why displacement can be zero while distance is large. 

Ending at the same point you started

400

  • 400: What is the difference between the initial and final positions called?

Displacement

400

  • 400: Give an example of describing an object’s position in two dimensions.

  • A house is one block southeast of yours

400

  • 400: True or False: Motion always means moving far from the starting point. 

False

400

  • 400: A baseball player runs 360 ft around the bases. What is the displacement? 


0 ft

400

  • 400: Explain how two people could describe the same object’s position differently

  • (They’re using different reference points)

500

  • 500: Give an example of a reference point. 

School, Home, etc

500

  • 500: True or False: Reference points do not affect how you describe location.

False

500

  • 500: Why is it important to specify a reference point when describing motion? 

(Because motion is relative to that point)

500

Give an example where distance and displacement are different.  

Walking in a square

500

  • 500: Describe the difference between position and motion. 

(Position is location relative to a point; motion is change of position)
