Answer #1

please Up Vote. otherwise , just comment down the problem/confusion . I will get back to you asap.

Please note that in my solution I have shown explicitly that what will be the unit of slope in both cases for your reference

1. if acceleration - y axis

mass - x axis

2. mass - y axis

acceleration - x axis .

I did a lab on Newton’s second law. The procedure went something
like this
Procedure:
1.) Tare the force sensor attached to the cart.
2.) Attach 100 g to the string and attach the other end to the
force sensor atop the cart.
3.) Allowing the weight to hang freely, from the end of the
string that is attached to the force sensor, start recording data
while holding the cart in place to capture T0
4.)Release the cart, this allows...

1. In Newton’s 2nd law experiment, a student measured
the acceleration of the glider and the weight of the hanging mass.
In this experiment, the air track was on and there was no drag
force acting on the glider. The student results are shown
below:
F (N)
a (m/s2)
0.100
0.100
0.200
0.250
0.300
0.450
0.400
0.600
0.500
0.800
a. Use Excel to plot the data and use the linear fit to find the
slope.
b. Use your findings to...

A cart of mass m1(pictured) is free to move nearly frictionless
up a ramp at angle θ. A small mass m2 hangs from a string that runs
over a pulley and connects to m1. We will determine the
acceleration of the cart m1 over a known distance x,then plot the
acceleration of m1 as a function of the hanging mass m2.
a) The hanging mass will create a constant pulling force to
accelerate the cart up the ramp. Using Newton’s...

Exploration 2.1 Suppose the cart and masses can be changed by
adding masses to the cart. Sketch a graph of the acceleration
plotted vs. cart masses in the space below based on your equation
in part 1.1e. Equation is mhg=(mc+mh)a. a=mhg/mc+mh
Exploration 2.2 If you were to take data, measuring the
acceleration of the cart for different masses added to the cart,
what could you plot that would give you a straight line? What would
be on the x-axis? What...

A cart with a total mass of 300g is on low-friction track with a
string attached to mass of 100g hanging over a low friction pulley?
The cart and hanging weight are held in place and then released. 1.
what is the acceleration of the cart after it is released Express
your answer in SI units keeping the correct number of significant
figures.

A group of students performed the same "Newton's Second Law". They
obtained the following results:
m1(kg)

where m1 is the value of the hanging mass
(including the mass of the hanger), v1 is the
average velocity and t1 is the time at which
v1 is the instantaneous velocity for the first
photogate, and v2 is the...

The current i(t) in amps as a function of time
t in seconds is plotted above for an ideal L-C circuit
(zero resistance). At t = 6 s as indicated by the dashed
vertical line, the current is i = –0.84 A. The current
amplitude is 3 A. Approximately what percentage of the total energy
in this circuit is stored in the magnetic field of the inductor at
this point?

Hooke’s Law Hooke's Law For this lab you need to plot a graph of
Force( y axis) versus elongation (x axis) for a spring. The graph
of force vs elongation for spring should be a straight line
(Hooke's law). From the slope determine the elastic constant, k. If
you are not using Excel, draw your graphs by hand, scan or take a
picture and insert the graph in the lab report. Your graph should
have a title, and the axis...

This question is from a physics lab on Gravitational
Acceleration.
Given that each tick from a spark timer occurs at one sixtieth
of a second, get the slope in units of cm/sec^2. Compare your
answer with the standard value of 980 cm/sec^2by computing the
percentage difference.
Our lab data for instantaneous velocity gives us a best fit line
with and equation of y=.5223 + 2.0692 giving a slope of .5223
cm/ticks^2. This conversion seems as if it should be pretty...

4. Use the formula for the acceleration found at point 3 to
calculate the “calculated acceleration” in Data Table for any given
hanging mass m.
5. Determine the percentage difference between the values of
acceleration calculated using the equation at point 3) and the
values measured using the experiment.
%error = | ameasured −
acalculated| ×100 /

and write them in the table.
PART III: CONCLUSIONS
1. Give a reasonable explanation for your percent difference.
What can be the...
