1. What is the Power Equation?

The power equation (P = F × v) calculates the instantaneous power output in watts when a force is applied at a certain velocity. For stationary bicycles, this helps quantify the work being performed by the cyclist.

2. How Does the Calculator Work?

The calculator uses the power equation:

Where:

• \( P \) — Power in watts (W)
• \( F \) — Force in newtons (N)
• \( v \) — Velocity in meters per second (m/s)

Explanation: The equation shows that power output increases linearly with both force and velocity. Doubling either force or velocity will double the power output.

3. Importance of Power Calculation

Details: Measuring power output is essential for training optimization, performance tracking, and comparing workout intensities. It provides an objective measure of effort that's independent of heart rate or perceived exertion.

4. Using the Calculator

Tips: Enter the force applied to the pedals in newtons and the velocity of the pedals in meters per second. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure force on a stationary bike?
A: Many modern stationary bikes have built-in force sensors. Alternatively, you can estimate based on resistance settings and pedal force.

Q2: What is a good wattage for stationary biking?
A: For casual cyclists, 50-150 watts is typical. Competitive cyclists may sustain 200-300 watts. Elite athletes can exceed 400 watts.

Q3: How does this relate to calories burned?
A: 1 watt = 1 joule/second. There are about 4.184 joules per calorie, so power output can help estimate energy expenditure.

Q4: Why use watts instead of RPM?
A: Watts account for both pedaling speed (RPM) and resistance, giving a more complete picture of workout intensity.

Q5: Can I use this for outdoor cycling?
A: The same physics applies, but measuring force and velocity accurately outdoors is more challenging without power meters.
