1-d Kinematics Simulation
1)Go to
2)Download the program or select “run now”, depending on your preferences.
3)Click on the “Charts” tab.
4)You may choose the initial position (xi), initial velocity (vi), and acceleration (a) of the person. Select a few numbers at random and click play. Try this a few times.
5)Complete the following table with numbers consistent with the description of the person’s motion:
Description of person’s motion / Initial Position (m) (do not choose ± 10 m) / initial velocity (m/s) / acceleration (m/s2)a)stationary at a position to the left of the origin
b)stationary at a position to the left of the origin
(again, this time with a change in one or more variables)
c)moving to the left with increasing speed
d)moving to the left with increasing speed
(again, this time with a change in one or more variables)
e)moving to the right with constant speed
f)moving to the right with constant speed
(again, this time with a change in one or more variables)
g)moving to the left with decreasing speed, then moving to the right with increasing speed
h)moving to the left with decreasing speed, then moving to the right with increasing speed (again, this time with a change in one or more variables)
i)moving to the right with increasing speed
j)moving to the right with increasing speed
(again, this time with a change in one or more variables)
6)What is the general relationship between the graph of the position and the graph of the velocity? In other words, if you have a graph of position as a function of time, how do you make a graph of velocity as a function of time?
7)What is the general relationship between the graph of the velocity and the graph of the acceleration? In other words, if you have a graph of velocity as a function of time, how do you make a graph of acceleration as a function of time?
8)What is the relationship between the signof the velocity and the sign of the acceleration when the speed is increasing?
9)What is the relationship between the sign of the velocity and the sign of the acceleration when the speed is decreasing?
