The physics
Power is how fast energy flows: joules per second, measured in watts. Same work done in half the time means double the power.
Power climbing stairs: 2,200 J in 5 s
Answer: power = 440 W (in horsepower 0.59 hp).
What we know
- Work / energy: 2200 J
- Time: 5 s
Step by step
- Given
- W = 2200 J, t = 5 s
- Formula
- P = W / t
- Substitute
- P = 2200 / 5
- Result
- P = 440 W
All results
| Power | 440 W |
|---|---|
| In horsepower | 0.59 hp |
