34. Homework / After quiz – COPY THESE DIRECTIONS INTO YOUR PHYSICS NOTEBOOK!
Write a short paragraph (4-6 sentences) explaining a situation where energy is converted / transformed within a system. In other words, describe a situation that involves The Law of Conservation of Energy. You MUST include a picture (sketch) with your paragraph and the picture MUST be labeled. (Sample labels may include phrases such as:
High KE, Low PE
Max PE
Max KE
PE increasing, KE decreasing
Etc.
Do this assignment in your PHYSICS NOTEBOOK on a clean page! You may NOT use a skate park or roller coaster.
