Physics Thursday 11-8 Finish Lab Info gathering Work on calculations, write-up Any old homework See Play

Finish Gathering information With the rubber-band With the wood and paint stirrer

Finish Calculations Will want the calculations done in a neat sequential manner on a separate piece of paper All group members have the same calculations for the wood launch and the farthest rubber-band launch Each individual will have additional calculations on a 2nd rubber-band launch different from the rest of the group

Descriptions In addition to the calculations, write a concise description of the set-up for the most successful rubber-band shot. Write a paragraph indicating the most significant sources of error affecting the calculations. Be specific in your description. Don’t say “ measuring”, but indicate how error might have been introduced for specific measurements

Percent Error for angle Wood-Paint stirrer part Indicate the % error difference between the calculated angle of launch and the initial angle of the paint stirrer │calculated angle – paint stirrer angle │ X 100 Paint stirrer angle

Mass values Measure the mass values of your marshmallow shot and the paper shot Visit each group and record their paper shot mass value and their farthest range value. Write a brief statement indicating if you believe there is any relationship between the mass of the shot and the range it travels. Explain your position.

What is due for the lab 1) The paper with all the information 2) Calculations for the wood/stirrer projectile 3) 2 sets of calculations for the rubber-band projectile Max range projectile 2nd individual projectile Description of how the group shot the rubber-band Detailed paragraph on sources of error Percent error calculation for wood/stirrer projectile
