Study Notes
Work and Energy
- Work is different in everyday life and science
- Everyday life: useful physical or mental labor is considered work
- Science: work involves a force causing displacement
- If no displacement, no work is done, even if effort is expended
- Activities like playing, talking, watching—not considered work (scientifically)
- Examples include pushing a stationary rock, standing with a heavy load, climbing stairs/trees—work is involved if there's displacement
