I have to do a lab for my physics class that is online this is the link below. I have attached the worksheet that I have to do. I just need help completing the worksheet.  https://campus.toolwire.com/construct.asp?pid=UPX&mode=EnterLabName

Lab 8: Newton’s Second Law
Purpose
To investigate through graphing and data analysis how force, mass, and
acceleration are related
Background
Newton’s second law of motion states that the acceleration of an object
depends on the object’s mass and the net force applied to the object. The law
can be written mathematically as Force = Mass x Acceleration or F = m x a.
This equation can also be rearranged.
Acceleration =
Force Mass
The relationship between these variables can be used to explain the mechanics
involved in many collisions, from football tackles to car crashes. It is also useful
to keep in mind when figuring out how to accelerate quickly or how to create
the greatest force with the least amount of effort!
Skills Focus
Graphing, predicting, interpreting graphs, controlling variables, drawing
conclusions
Procedure
1. Start Virtual Physics and select Newton’s Second Law from the list of
assignments. The lab will open in the Mechanics laboratory.
2. The laboratory will be set up with a ball on a table. Attached to the ball is a
rocket used to push the ball across the table. There is no friction. In this
experiment, you will collect position and velocity data as the ball moves
across the table. Then you will make position and velocity graphs.
3. Click on the Lab Book to open it. Click on the red Recording button to start
recording data. Start the ball rolling by clicking on the Force button. Observe
what happens as the ball rolls across the table. The force is set to 10 N and
the mass of the ball is 2 kg. Does the ball speed up? The experiment will stop
automatically when the ball has reached the end of the table. You will see a
link appear in the lab book containing the position and velocity versus time
data of the ball rolling across the table. Double click next to the link to label
the line with the force and mass.
4. Click the Reset button to reset the experiment back to the beginning. Use the
Parameters Palette to change the rocket force and repeat Step 3 for two
different forces. Record the forces in the table on the next page.

like if the ball is accelerating?

5. Now observe what happens to the ball’s speed and acceleration when you
change the mass. Click the Reset button to reset the experiment back to the
beginning. Use the Parameters Palette to change the mass of the ball. Make
sure the force is set to 10 N, and repeat Step 3 for two different masses. Don’t
change the force for these experiments. Record the masses in the table.

Newton’s Second Law
1. Graphing Using the data in each of the data links in your Lab Book, draw
the velocity versus time graphs on the grid below. You will be plotting the
velocity of the ball versus the time as the ball crossed the table. Label the
horizontal axis as Time (s) and the vertical axis as Velocity (m/s). Choose a
scale for your graph that fits your data. The first data point will be (0 s, 0 m/s).
This is the time and speed of the ball when it started rolling. Plot ten points
for each ball. Connect the data points using a different color for each
experiment. Label each line with the force and mass of the ball.

2. Open each of the links and record the final velocity and the time it took to
reach that velocity in the table. Note: record the time when the ball first
reaches the end of the ramp—there may be another data point after that, but
just take the time when it reaches the end.
3. Interpreting Graphs How do the velocity versus time graphs show that
the balls are accelerating?
Which ball accelerated the most?
4. Acceleration is a measure of how much the velocity is changing over time.
This is expressed in an equation like this: Acceleration = Change in speed/
time interval. Calculate the acceleration of each of the balls using this
equation. Each ball started at 0 m/s. Record your calculations in the table on
the previous page.
5. Another way to calculate acceleration is to use Newton’s Second Law,
solved for the acceleration. Do your calculations for acceleration in #4 above
match what you would calculate using Newton’s Second Law?

6. Graphing Using the calculated data from your data table, draw a force
versus acceleration graph on the grid below. You will be plotting the applied
force on the ball versus the observed acceleration as the ball crossed the
table. Label the horizontal axis Acceleration (m/s2) and the vertical axis Force
(N). Just use your first three data points, collected in procedure step 4, which
were all performed on the same ball. Choose a scale for your graph that fits
your data.
