Spring Forces and Pulley Systems

Learning Goal 3.1 I can apply energy conservation to closed systems, and can reason about energy transfer between systems.

So far in this unit we've learned about how force, gravity, energy, and work are all related. I understand most of the equations we've learned, but applying them had been a bit difficult for me, as it's not always clear when and which equation to use. Deepening my understanding of the concepts behind these equations will probably help me fix this issue. Both the pulley systems and spring forces activity helped me understand that work is the area on a graph bounded by a force times distance diagram. In the spring activity it was interesting to see how distance stretched varied among the springs depending on the force applied.

Unit 2 Project

Learning Goal 2.2: I can reason and make quantitative predictions about real and virtual images formed by lenses and mirrors.

For my Unit 2 project, I chose to make a poster. The poster will cover the differences between real and virtual images and the difference by converging/diverging lenses and mirrors. Another thing I hope to add is predicting the magnification, orientation, and position of the images formed through mirrors and lenses.
