Distance/Position vs. Time

 

 


 

Experiment Question:

  1. How does the speed of an object affect the slope of the line in a distance/position vs. time graph?

 

Vocabulary:

  • Reference Point: A place or object used for comparison to determine if something is in motion.  The reference point explains the position of the object.
  • Position:  The location of an object compared to the reference point.

Part 1: Constant Speed

The reference point is the chair with the rubber band.

 

                                    Distance/Position vs. Time Graph

 

 

 

  • Constant Slope
  • Linear Graph (straight line)
  • As distance increases, so does the time
  • Positive Slope
  • From dot to dot, the line is equal distances.

  • Non-linear graph (not a straight line)
  • Positive Slope
  • As the time increases, the distance between the points increase too.
  • The slope increases (like becomes steeper or travels upward)

                                        Distance/Position vs. Time Graph


 
  • The slope is positive
  • As the time increases, the distances between the dots increase
  • Slope is decreasing
  • Non-linear graph (curved graph)

Slope is increasing
 

2 to 4 m


 


 

Object is slowing down
 


 

Slope decreases
 

4 to 6 m


 

 

Object moves at a constant speed
 

 

Slope stays the same

6 to 8 m


 

 

Object is speeding up
 

 

Slope is increasing

Did the slope increase, decrease, or stay the same?


 

 0 to 5 min

5 to 10 min

 

Object is moving at a constant rate

 

 

Slope stayed the same
 

 
10 to 15 min

 Slope increased

15 to 20 min

Object is slowing down

 

 

Slope decreased

20 to 25 min

 

Object is speeding up

 

Slope increasing

25 to 30 min

 

Object is slowing down

 

Slope decreased

 

 

 

 

 

Part 5: Summary

 

 

Partner 1 Summary

We set up 3 different experiments to determine whether the speed of an object affects the slope of a line.

The speed of an object affects the slope of a line, you can easily tell this by looking at graphs we made durring

this experiment. When an object speeds up, the slope will be increased (the line will start to become steeper). If

the object stays at a constant speed, the slope will stay the same (the line will continue to look the same). When an

object slows down, the slope will decrease (the line will start to drop. The angle of the line will be less than before.)
