physics 1401 lab exam ACTUAL UPDATED QUESTIONS AND CORRECT ANSWERS
In physics lab, students are asked to design an Using a projectile launcher, shoot the ball upward. Measure and determine the
experiment to study the Conservation of Energy. Which initial and final velocities and vertical positions.
of the following data gathered in the experiment can be
used for this purpose?
Students have conducted the Behavior of a Gas Study the pressure dependence on volume
experiment in a physics lab. The equipment is pressure
sensor, syringe and data collection device (LabQuest). At
first, they placed the syringe at 5 mL and then connected
to the pressure sensor. As they varied the volume, they
recorded the pressure and the volume in the syringe.
They have plotted the data. The pressure vs volume
graph is shown on the right.
What is the purpose of this experiment?
Which result can be derived from this experiment? . Pressure and volume have an inverse relation
, During the lab experiment, the velocity of sound in dry air 0.51%
at 0C is measured and found to be 333.1 m/s. The
accepted value for the velocity of sound in dry air is
331.4. What is the percent error?
In an Atwood's machine experiment, students are asked Legend
to draw the velocity versus time graph of the moving
mass on their lab notebook. Which is the NOT required
element in the graph?
Kim is writing physics lab report for the "Force Table" Prediction
experiment. After reviewing her report, she noticed that
there is some unnecessary information. Some of the
section headings of Kim's report are listed below.
Indicate the section, which she could eliminate from her
report.
Kim is writing physics lab report for the "Force Table" Summary of the Procedure
experiment. After reviewing the conclusion section, she
noticed that there is some unnecessary information.
Indicate the information, which she could eliminate from
the conclusion
What is the purpose of physics lab logbook/notebook ? Record any information during the lab
A "Purpose" section in the lab report contains Objectives of the experiment
An "Analysis" section in the lab report contains Calculations
There are three different methods of vector addition: experimental, analytical, and graphical.
lab 1 objective vector addition In this lab, students will practice graphical and analytical vector addition.
the x and y components of a vector can be calculated as 𝐴𝑥 = 𝐴 cos 𝜃 and 𝐴𝑦 = 𝐴 sin 𝜃
𝑅𝑥 = 𝐴𝑥 + 𝐵𝑥
𝑅𝑦 = 𝐴𝑦 + 𝐵y
The magnitude and direction of 𝑅 can then be found as 𝑅 = √𝑅𝑥 ^2+ 𝑅𝑦 ^2
θ = tan−1 𝑅𝑦/ 𝑅x
