1. What is Force × Velocity Power?

Definition: This calculator computes mechanical power as the product of force and velocity.

Purpose: It helps engineers, physicists, and students determine the power required or generated in mechanical systems where force is applied to moving objects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Power (Watts, W)
• \( F \) — Force (Newtons, N)
• \( v \) — Velocity (meters per second, m/s)

Explanation: Power is calculated as the instantaneous product of force and the velocity in the direction of the force.

3. Importance of Power Calculation

Details: Understanding power in mechanical systems helps in designing efficient machinery, calculating energy requirements, and analyzing system performance.

4. Using the Calculator

Tips: Enter the force in Newtons and velocity in meters per second. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units does this calculator use?
A: The calculator uses SI units - Newtons for force, meters per second for velocity, and Watts for power.

Q2: Can I use this for rotational systems?
A: For rotational systems, use torque × angular velocity instead of force × linear velocity.

Q3: What's a typical force value?
A: Force values vary widely - from fractions of a Newton (small objects) to thousands of Newtons (machinery).

Q4: How does this relate to electrical power?
A: 1 Watt of mechanical power is equivalent to 1 Watt of electrical power, just in different forms.

Q5: What if the force and velocity aren't in the same direction?
A: Use only the velocity component in the force direction (P = F × v × cosθ where θ is the angle between them).
