Use your velocity-time graph to find the acceleration of your system. Use the ring-stand clamp to attach the "Smart Pulley" to the ring stand. Click on the axes labels of the graph window to change the horizontal quantity to time, t, and the vertical quantity to velocity, v.

Add the smallest mass available 10 grams to one of the masses on your apparatus. Attach one end of your string to a gram mass. Put graph and equation in your lab book Part 2: Set your phone to record your video at the greatest frame rate it is capable of recording.

Show your results to your teacher and if the results are good, you may start the live part of the experiment. If m1 is greater than m2, determine the acceleration of the two masses when released from rest. Watch the motion of the two bottles. In the Timing menu, select "Trigger on Gate" it should get a check mark.

The ULI Timer software will hold only one data set at a time, so something has to be done with the data you have just collected. Transfer this lab setup into your lab book.

This opens a new window labeled Surprise! Bring bottle 2 down to table level and then release the bottle. Note that if the string and pulley were not massless, this problem would become considerably more involved. Put graph and equation in your lab book. Feel free to borrow my tripod when you are ready to record.

Info Developed by George Atwood in If the pulley is attached correctly, you should see the icon labeled "1" in the upper-left corner of the screen change from dark to light to dark as the photocell is covered and uncovered by a spoke of the wheel.

The machine typically involves a pulley, a string, and a system of masses. In the Window menu, select "New Table". Notice that when you release the masses, the system accelerates - even with a very small mass difference.

Copy your data to the clipboard, and paste it into a "New Data Set" in the Graphical Analysis program. Record these masses in your notebook and then carefully set up your system with mass 1 at the highest point, mass 2 at the lowest point and a meter stick clearly placed right near one of the two bottles.

Use the mouse to select both data columns from your data table. The ULI Timer has the capability to graph the data, but instead of learning how to use it, it might be more efficient to transfer the data to the "Graphical Analysis" software you already know how to use.

Your data-table window should look like the one shown at right.

Be sure that the interface is properly attached to the computer, and that the power supply is plugged in. You have a velocity vs. Be sure to record the masses used for each trial. Copy the data to the clipboard.

Load the "ULI Timer" software. Therefore, its average velocity during each time interval is 0. How closely do the "theoretical" and "experimental" accelerations agree?AP Physics Lab The Atwood Machine. Discussion: The "ideal" Atwood machine consists of two masses, M 1 and M 2, connected by a massless, inelastic string which passes over a frictionless pulley.

The diagram at right shows an Atwood machine, along with a free-body diagram for each mass, and the resulting equations of motion.

I would expect no86%(14). Newton's Laws: Modified Atwood Machine Participants: Sam, Josh, Newell Purpose: In this lab, we examine a modified Atwood machine where one of the masses moves horizontally along a frictionless surface, rather than killarney10mile.com purpose of this lab is to explore and prove, to some extent, Newton's laws, specifically the second law:.

The purpose of this lab is to understand the relationship between the acceleration of an object and the applied force. Atwood's machine Modified Atwood's machine.

AP PHYSICS 1 INVESTIGATIONS AP Physics 1 Investigation 2: Newton’s Second Law What factors affect the acceleration of a system? In this investigation, students use a modified Atwood’s machine. Atwood’s machines are systems with two masses connected by a cable and pulley.

Atwood Lab. Purpose: The purpose of this lab is to determine how the ∆m and the ∑m affect the acceleration of the Atwood system. We will then use this formula for a live trial of the Atwood Machine to approximate the acceleration due to gravity on earth.
