What variables affect the impact force in a collision and in what manner do they affect the force? Wherever relevant, percent difference calculations should be considered. The Discussion of Results should include a discussion of the manner in which the evidence supports the conclusion specific data results should be referenced. The Conclusion should respond to the Purpose of the Lab (as always).

The Data section should include a sketch of any relevant graphs obtained from the LabPro interface software comments, descriptions and relevant quantitative information should be provided for each graph. To compare the impulse experienced by an object to the resulting change in momentum of the object.Ī complete lab write-up includes a Title, a Purpose, a Data section, and a Conclusion/Discussion of Results. How does the impulse experienced by an object in a collision compare to the resulting momentum change of that object? Being Impulsive About Momentum Change Lab Use an organizational system and label all work. They should be clearly organized and easy to find. Click OK.The following items should be in the Momentum and Collisions portion of your notebook. Choose Motion Sensor,and set the trigger rate to 100. In the Sensor Properties window, choose Measurement, then de- select Position and Acceleration, so only Velocity is selected. Connect the yellow motion sensor plug into digital channel 1, and the other plug into channel 2. Under Measurement, de-select all choices and select Force (only Force should be checked). In the Sensor Properties window, choose General, then select Fast Force Changes, and increase the sample rate to 1000 Hz. Connect the Force Sensor lead to Channel A on the Science Workshop Interface box. Launch the Data Studio program, choose Create Experiment, select Force Sensor, and Motion Sensor. Program Selection and Preparation Turn on the Pasco Science Workshop Interface, then the computer, and login. What was the total impulse on the ball?

A 4 kg ball moving at 3 m/s bounces off a wall and is observed to be moving at 3 m/s in the opposite direction.

(Hint: For parts 1 to 4 above, graph the force vs. The force decreases linearly to 0 in 2 seconds. The force stays constant at 8 Newtons for 3 seconds. The force grows linearly from 0 to 8 Newtons in 2 seconds. A force in the positive x direction acts on the mass for 7 seconds as follows: a. A 4kg mass is initially moving in the x direction at 5 m/s. 12/04/20 1 Pre-Lab Assignment Complete the following problem, using the impulse-momentum relationship. In addition, the initial and final (maximum and minimum) velocities can be obtained, making it easy to calculate initial and final momentum, and test the impulse-momentum relation.

A statistics package is used to integrate the force versus time curve to obtain the impulse. The computer graphs force versus time, and also the cart’s velocity versus time. A motion sensor detects the position of the cart versus time, enabling its velocity to be calculated as a function of time. In this experiment, a moving cart collides with a stationary “force sensor.” The force sensor measures the collision force as it varies with time throughout the collision.

The impulse of a resultant force from time t1 to time t2 is When the force is plotted versus time, the impulse is the area under the curve between t1 and t2.
