All lab work should be completed in your course notebook and be recorded on the right side of the open notebook. If you come to the end of the page, you must of course turn the page over and continue writing on the back of the page on the right side of the page of the open notebook. Any accompanying sheets must be taped, glued, stapled or somehow attached to the lab notebook; scotch tape is always available in the room.

Scoring Rubrics for each lab are available online. These will also be distributed in class a couple days prior to notebook collection. View:

Lab NLV1:  Pass the Water

Question: 
Under what conditions is water most likely to spill from a pan when the pan is carried around an oval race track?

Purpose: 
To carry a pan of water around an oval race track in an effort to determine the conditions under which the water is most likely to be spilled from the pan.

A complete lab write-up includes a Title, a Purpose, a Data section (which includes a diagram of the oval track and identified locations of water spillage), a Conclusion and a Discussion of Results.  As usual, the Conclusion should answer the question proposed in the purpose of the lab.  The Discussion of Results should include a discussion of the relationship between your findings and Newton's first law of motion.





Lab NLV2: Wait! Hmmm. Gee.

Question:
What is the relationship between the mass of an object and the force of gravity which acts upon the object?

Purpose: 
To determine the mathematical relationship (i.e., the equation) which relates an object's mass (m) to the force of gravity (Fgrav) that acts upon the mass.

A complete lab write-up includes a Title, a Purpose, a Data section, a Conclusion, and a Discussion of Results. The Data section should include a table of data and a plot of the data;  the results of a linear regression analysis should also be included.  Class data should be reported. The Conclusion should respond to the question raised in the Purpose of the lab (as always). The Discussion of Results section should reference the Data section and discuss the supporting evidence for the conclusion.  An error analysis should be included.





Lab NLV3: F-m-a Relationship

Question: 
What effect does varying force and varying mass have upon the acceleration?

Purpose: 
To use experimental data to determine the mathematical equation which relates force, mass and acceleration.

A complete lab write-up includes a Title, a Purpose, a Data section, a Conclusion, and a Discussion of Results. The Data section should include two acceleration-force graphs (one for each mass) with a sketch of the plotted points, the best estimate on the slope of the line, and an indication of the mass of the cart.  Class data should be included for the other lab groups.  The Conclusion should respond to the question raised in the Purpose of the lab (as always). The Discussion of Results section should reference the Data section and thoroughly discuss the supporting evidence for the conclusion.  The effect of mass and the meaning of the slope of the line should be clearly discussed.




Lab NLV4: Map Lab

Question:
What is the final destination and the resultant displacement for each of three sets of displacement vectors?

Purpose: 
To identify the final destination and the resultant displacement for three sets of two or more displacement vectors.

A complete lab write-up includes a Title, a Purpose, a Data section, a Conclusion, and a Discussion of Results. The Data section should include the provided table; the table should be completed using the colored Northfield Township map. The Conclusion should identify the three trips that were taken and the final destination (e.g., intersection or specific landmark).  The Discussion section should include a trigonometric analysis (Pythagorean theorem and SOH CAH TOA) of one of the three trips. The analysis should include a diagram of the vectors being added together in head-to-tail fashion; it should also include careful work showing how the magnitude and direction can be predicted using trigonometric functions. The predicted value should be compared to the measured value.





Lab NLV5: As the Crow Flies Lab

Question:
What is the as-the-crow-flies displacement from the Physics room (Room 332) to an assigned location in the school?

Purpose
To determine the as-the-crow-flies displacement from the Physics room (Room 332) to a designated location within the school.

A complete lab write-up includes a Title, a Purpose, a Data section, and a Conclusion. The Data section should include a table of the magnitude and the direction of each of your hallway displacements used to reach your assigned destination. The number (or letter) of the destination should be indicated. This section should also include a diagram that includes a sketch of the individual vectors being added in head-to-tail fashion; vectors should be labeled with a magnitude; the resultant should be sketched and labeled as R. A trigonometric analysis should be performed to determine the magnitude and direction of the resultant. The analyses should be organized, labeled and follow-able. All work should be shown for your trigonometric analysis. The Conclusion should respond to the question raised in the Purpose; this can be done with 1 sentence.





Lab NLV6: Equilibrium Lab

Question: 
What is the result of conducting a force analysis on an object at equilibrium?

Purpose: 
To conduct three different equilibrium analyses in order to determine the net force upon three different objects.

A complete lab write-up includes a Title, a Purpose, a Data section, and a Conclusion/Discussion of Results.  The Data section should include a diagram of the three situations being analyzed with the magnitude and direction of all forces clearly stated on the diagram;  a labeling convention (e.g., A= , B= , C= , etc.) should be used to distinguish between the forces. Calculations and analysis should be clearly shown. A net force should be determined. The Conclusion/Discussion should identify the calculated net force for the three situations and should include an error analysis for each situation.




Lab NLV7:    Exploring Inclined Planes


Question: 
How is the weight of an object mathematically related to the component of the weight directed parallel to the inclined plane?

Purpose: 
To determine the mathematical equation which relates the weight of an object to the component of the weight that is directed parallel to an inclined plane.

A complete lab write-up includes a Title, a Purpose, a Data section, a Conclusion, and a Discussion of Results.  The Data section should include a diagram of the inclined plane to which you were assigned, with measurements included on the diagram.  Class data for the various incline angles should be recorded.  Some form of analysis leading up to an equation should be documented in the Data section.  The Conclusion should state the mathematical relationship in both words and an equation. The Discussion of Results should thoroughly explain the logical connection between the collected data and the conclusion.
