High Phives all around!
Phinish any calcs and finish presenting your results on your board. I have highlighted the board requirements below.
Learning Goal: I can describe and calculate the amount of work done to an object based on the factors that affect it.
Today: It’s All Uphill Lab
Given: Scale/force probe, dynamics cart, mass (500g), paper clips, string, meterstick/ruler, protractor, board/ramp, graph paper
Find: Determine the effect of the angle of incline upon the force needed and upon the work done when pulling a cart up an incline to the same height at a constant speed.
Groups should produce
- Data table showing incline angle, force, displacement and work for each trial.
- Graphs on graph paper or spreadsheet of force vs. incline angle and displacement vs. incline angle. Each graph should include a best-fit line.
- Use your data to write a short conclusion. Use the data and the purpose of the lab to guide your conclusion.
- Choose equal angle intervals for the best data. Start with the lowest angle, choose your height, then keep that height constant for the rest of the lab.
- Keep your angles from 20-70 degrees for best results.
- Use a clothespin on a ring stand to mark your height. Makes it easy to keep track through multiple trials.
- If you (or someone at home) is not or will not satisfied with your recent test results, set up an appointment for GPS or after school ASAP to discuss a retake.
- Wed. 2/28: PHYSICSPALOOZA after school in this room!
- Due Fri. 2/23: Take Cornell or other organized format notes FOR UNDERSTANDING. Remember that good notes include diagrams, text language, sample equations, etc. Notes should come from any of the following:
