Question

Larry and Balky set up an experiment to analyze the motion of a marble as it rolled down an incline. They started the marble at the top of the ramp and set up photogates to collect data as the marble rolled down the ramp. Which graph format would allow Larry and Balky to calculate instantaneous velocity using slope? A) Velocity on the y-axis, time on the x-axis B) Distance on the y-axis, time on the x-axis C) Time on the y-axis, distance on the x-axis D) Velocity on the y-axis, distance on the x-axis

Answer 1

A

Step-by-step explanation:

slope is calculated using rise over run

Answer 2

Option B

Step-by-step explanation:

The instantaneous velocity = Change in position/Time taken

The slope of the graph should give instantaneous velocity.

Slope of a graph = Change in value of Y -axis / Change in values of X -axis

Comparing both the equations

Change in value of Y -axis = Change in position

Change in values of X -axis = Time taken

So position values should be on the Y axis and Time values should be on the X axis.

Distance on the y-axis and time on the x-axis.

So, option B is the correct answer.
