Measure the mass of your dynamics cart and record the value in the Data Table.
Measure the mass of your dynamics cart and record the value in the Data Table. Place the track on a level surface. Confirm that the track is level by placing the low-friction cart on the track and releasing it from rest.
It should not roll. If necessary, adjust the track. Attach the elastic cord to the cart and then the cord to the force sensor. Choose a cord length so that the cart can roll freely with the cord slack for most of the track length, but be stopped by the cord before it reaches the end of the track.
When the cord is stretched to maximum extension the cart should not be closer than 0. Use the black link cable to connect the interface to the TI Graphing Calculator.
Firmly press in the cable ends. If CH 1 displays the Force Sensor and its current reading, skip the remainder of this step.
To do this, a. Select OK to return to the main screen. Zero the Force Sensor. Remove all force from the Force Sensor. Set up the calculator and interface for data collection. Select OK twice to return to the main screen. Practice releasing the cart so it rolls toward the Motion Detector, bounces gently, and returns to your hand.
The Force Sensor must not shift and the cart must stay on the track. Arrange the cord and string so that when they are slack they do not interfere with the cart motion. You may need to guide the string by hand, but be sure that you do not apply any force to the cart or Force Sensor.
Keep your hands away from between the cart and the Motion Detector. As soon as you hear the interface beep, roll the cart as you practiced in the previous step. Study your graphs to determine if the run was useful: Inspect the force data.
If the peak is flattened, then the applied force is too large. Repeat your data collection with a lower initial speed.
Confirm that the Motion Detector detected the cart throughout its travel. If there is a noisy or flat spot near the time of closest approach, then the Motion Detector was too close to the cart. Move the Motion Detector away from the cart, and repeat your data collection. To collect further data, return to Step Once you have made a run with good distance and force graphs, analyze your data.
To test the impulse-momentum theorem, you need the velocity before and after the impulse. To find these values, a. Now you can select a portion of the velocity graph for averaging. Now set the upper bound: Move the cursor to the right edge of the approximately constant- and negative-velocity region.
Read the average velocity before the collision vi from the calculator. Record the value in your Data Table. In the same manner, determine the average velocity just after the bounce vf and record this positive value in your Data Table.
Calculus version Now record the value of the impulse.is a vector quantity (since force is a vector and time is a scalar). Impulse-Momentum Theorem. The impulse-momentum theorem states that the change in momentum of an object equals the impulse .

In this lab, the first aluminum disk (without non-slippery pads) will be set at an initial angular speed.
The second disk (with non-slippery pads) will be dropped onto the spinning platter. The angular speed will be monitored and recorded by the LoggerPro program, ".

Nov 20, · Impulse – Momentum Lab November 20, by danielrafala Purpose: The Purpose of this Lab was to try to explore the Impulse – Momentum Theorem and hopefully obtain data that would support the idea that an applied impulse will cause a change in momentum, and show how the Impulse is equal to that of an objects change in momentum.
