- C vs. D
- This is a formal lab report. Refer to the laboratory
manual.
- Include an Excel plot of Circumference as a function of Diameter.
- Calculate
the percent difference between the slope of your graph and the
value of pi.
- Explain the y-intercept of your graph in terms of error
analysis.
- Dozer Challenge
- Ticker Tape Timer
- This is a formal lab.
- Be sure to include your raw and analyzed data for both experiments.
- Include
both d-t and v-t graphs with mathematical models for both experiments.
What do the mathematical models mean in the real world?
- Include
diagrams of the ticker tape for both experiments
- Compare your results for constant velocity and accelerated motion.
- Picket Fence Freefall
- This is an activity writeup.
- Complete all analysis and extension 1.
- Cart on an Incline
- This is an activity writeup.
- You do not need to complete any extensions.
- Projectile Motion
- This is a formal lab.
- You must complete extension 2.
- One bonus point will be awarded for getting the bearing into the target can and an
additional bonus point will be awarded for successfully completing extension 5 by getting
the bearing through the ring and into the target can.
- Rocket Science
- This is a formal lab.
- Show your experimental design, data and calculations for the following:
- initial velocity
- time of flight
- max height
- range
- Compare your calculated time of flight and range to your measured
max height and range. If they are different, explain why (really
think about this, it's more than just "error").
- Inertial Balance
- This is a formal lab.
- The purpose of this lab is to investigate the difference between
inertial mass, gravitational mass and weight.
- Be sure to include
a description of what an inertial balance is in your background.
What is its purpose? How is it used? Find and use
an image from the web.
Use proper citations!
- Show how you calibrated your balance.
- Include your graph of period [s] vs. mass [kg].
- Find the line of best-fit and the real world equation
to describe it. Is it linear? What does the equation
tell you? What does the slope mean? What does the y-intercept
mean?
- Experiment 1: inertial mass vs. gravitational mass
- Measure the inertial mass of the unknown mass using your
inertial balance and the equation from your graph.
- Measure the gravitational mass of the unknown mass using
a triple beam balance.
- How did your inertial mass measurements compare to your
gravitational mass measurements? Find the percent
difference between the two.
- What is the difference between inertial mass and gravitational
mass? Are they equivalent? How can you tell?
- Experiment 2: mass vs. weight round 1
- Hang your slug from the bottom of the tray with some string.
Now the balance is supporting its weight, but the mass is not
in the tray.
- Try to determine the mass of the slug. Is it different from
before? Is the inertial balance able to measure the mass when
set up this way? Explain in terms of the Law of Inertia.
- Are mass and weight equivalent? How can you tell? Justify
your answer based on the results of your experiments.
- Experiment 3: mass vs. weight round 2
- Support your slug with string such that it is in the
hole of the inertial balance, but its weight is not being
supported by the tray.
- Determine the inertial mass of the slug with it set up
this way. Is it different from when the slug just sat
in the tray? Can the inertial balance measure the mass without
supporting the weight?
