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.

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.
