Show your work. Include units at every step.
Sketch a graph of your data below. Label axes with variable name AND unit. Draw a best-fit line if appropriate.
Describe the relationship shown by your graph (direct proportion, inverse proportion, no relationship, other): _______________________________________________
Name the specific physics law or equation that describes your results (e.g., Newton's Second Law: F = ma, Conservation of Energy: KE + PE = constant). Explain how your data demonstrates this law:
If you have a theoretical or accepted value, calculate your percent error:
Restate your hypothesis, then report whether your data supported or contradicted it. Cite specific measurements as evidence. Identify one limitation of your experiment:
Name one technology, structure, or system in your community that works because of the physics principle you investigated today. How does a physicist's understanding of this principle make that technology possible?
