Bike Speed Equation:
From: | To: |
The bike speed equation (v = P/F) calculates a cyclist's speed based on power output and opposing force. It's fundamental in cycling physics and performance analysis.
The calculator uses the basic physics equation:
Where:
Explanation: This equation shows that speed is directly proportional to power and inversely proportional to opposing forces like air resistance, rolling resistance, and gravity.
Details: Understanding the relationship between power and speed helps cyclists optimize training, predict performance, and select appropriate gearing for different conditions.
Tips: Enter power in watts and total opposing force in newtons. Both values must be positive numbers. The result shows speed in meters per second.
Q1: How accurate is this calculation for real cycling?
A: This is a simplified model. Real-world cycling involves additional factors like wind, gradient, and bike mechanics.
Q2: What's a typical power output for cyclists?
A: Recreational cyclists might average 100-200W, while professionals can sustain 300-400W for extended periods.
Q3: How do I estimate total opposing force?
A: Total force includes air resistance (dominant at higher speeds), rolling resistance, and gravity (on hills).
Q4: Can I convert m/s to km/h or mph?
A: Yes - multiply m/s by 3.6 for km/h or by 2.237 for mph.
Q5: Why does speed increase linearly with power in this model?
A: This assumes constant force. In reality, air resistance increases with speed, making the relationship non-linear.
