PART I: NEWTON'S SECOND LAW
Step 1: Set-up
s is the variable used for displacement.
a
Cart mass (M) = 100 g
b
Hanging mass (m) = 1.0 g
c
Coefficient of friction = 0.000
d
Distance (s) = 0.100 m (Adjust the distance by dragging the light barrier (LB) with your mouse. Watch the distance, s, change as you move the barrier to the correct value.)
Step 2
Run the simulation and obtain data.
a
Click Start. Allow the simulation to run until it stops.
b
Click Record Data.
c
Record the time in Table 1.
d
Drag LB to a distance of 0.200 m.
e
Click Start. Do not click Reset.
f
Click Record Data and enter the time in Table 1.
g
Repeat the process, changing the distance each time, until you have 10 measurements and Table 1 is filled.
Step 3
Change the cart mass as indicated in Table 2 and rerun the simulation.
a
Click Reset.
b
Set the cart mass (M) to 250 g.
c
Drag LB to a distance of 0.100 m.
d
Repeat all parts of Step 2, recording these time values in Table 2.
Step 4
Change the cart mass and the hanging mass as indicated in Table 3 and rerun the simulation.
a
Click Reset.
b
Set the cart mass (M) to 100 g.
c
Set the hanging mass (m) to 4.0 g.
d
Drag LB to a distance of 0.100 m.
e
Repeat all parts of Step 2, recording these time values in Table 3.
Step 5
Answer the following questions on your worksheet.
a
If you increase the mass of the cart, while leaving the hanging mass unchanged, does the acceleration of the system increase, decrease, or stay the same?
b
If you increase the mass of the hanging weight, while leaving the mass of the cart unchanged, does the acceleration of the system increase, decrease, or stay the same?

Complete Table 1. Record all data to three decimal places (e.g., 4.000 or 6.325 or 0.000). Do not include units in your answer Table 1 (M= 100 g,m=1.0 g) If the data points of distance and time were connected smoothly on a graph, the curve would be a select. The line or curve formed is Select because the object is Select Complete Table 2. Record all data to three decimal places (e.g., 4.000 or 6.325 or 0.000).

a- if you increase the mass of the cart there is no change in accleration. the force that pulls the cart is same which is the hanging mas which is pulled by gravity.
b- yes the accelaration changes as when the mass of hanging block increases so is gravitational force and so is the tention in string attached. hence more force and more accleration.
