Reddit & Student Insights: What Aspirants Say About Work, Energy, and Power
Many students expressed their confusion regarding work and power because, based on the definitions, the physical quantities seem quite similar. A user posted about this on Reddit:
- “Power is work over time, but I have never really understood what that actually means. Also, why is power more useful than work when evaluating a machine?”
