Cycling Power to Speed Formula:
| From: | To: |
The cycling power to speed equation calculates velocity (v) from power (P) and force (F) using the fundamental relationship v = P/F. This simple formula is derived from the basic physics principle that power equals force times velocity.
The calculator uses the power to speed equation:
Where:
Explanation: The equation shows that for a given power output, speed is inversely proportional to the opposing forces. In cycling, these forces include air resistance, rolling resistance, and gravity on hills.
Details: Understanding the relationship between power and speed helps cyclists optimize their performance, estimate race times, and evaluate equipment choices. It's fundamental for training and race strategy.
Tips: Enter power in watts and force in newtons. Both values must be positive numbers. The calculator will compute the resulting speed in meters per second.
Q1: How is this different from more complex cycling power models?
A: This is the most basic form. More complete models account for air resistance (which increases with speed squared), rolling resistance, and gradient.
Q2: What's a typical force value for cycling?
A: On flat ground at moderate speeds, total opposing force might be 20-50N, increasing significantly with speed due to air resistance.
Q3: How does this relate to cycling on hills?
A: On climbs, gravity becomes the dominant force. The steeper the hill, the greater the gravitational force component opposing motion.
Q4: Why use this simplified calculation?
A: It demonstrates the fundamental relationship and is useful for understanding how changes in power or resistance affect speed.
Q5: How accurate is this for real-world cycling?
A: It gives a theoretical maximum. Real-world speeds will be lower due to additional factors like wind, rolling resistance, and drivetrain losses.
