Find your sticks for your new lab group. Start planning your lab - What measurements will you take? How? Will your data points be random or will you make measurements at regular intervals? What will you do to make sure you are achieving the Big Three #LabGoals?
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 work vs. incline angle. Each graph should include a best-fit line.
Assignment:
- If you (or someone at home) is not or will not satisfied with your test results, set up an appointment for GPS or after school ASAP to discuss a retake.
- Due Wed. 2/14: 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:
- APlusPhysics: Work (only up to 8:18, but future AP students may want to go further)
- Hewitt Drew-It Video: Work
- PhysicsClassroom part I, part II (you are not responsible for the angle or graph stuff in THIS class, but if you are curious or taking AP, you may want to look)
- Conceptual Physics text, Ch. 8: Section 8.1
