About This Tool
This free online Work, Power, and Energy Calculator is a versatile tool designed for students, teachers, and professionals in physics and engineering. It allows you to calculate work, power, and energy by providing any two of the following parameters: force, distance, time, work, or power. The tool performs real-time bidirectional calculations, updating all fields instantly as you type.
How It Works
The calculator uses fundamental physics formulas to establish relationships between different mechanical quantities:
- Work is calculated as the product of force and distance (Work = Force × Distance)
- Power is calculated as work divided by time (Power = Work / Time)
- Energy is equivalent to work in mechanical systems (Energy = Work)
Practical Applications

Frequently Asked Questions
Q: What is work in physics?
A: In physics, work is defined as the product of the force applied to an object and the distance over which it is applied, in the direction of the force. It's measured in Joules (J).
Q: How are power and energy related?
A: Power is the rate at which work is done or energy is transferred. Energy is the capacity to do work, while power is how quickly that energy is used or transferred.
Q: What units does this calculator use?
A: The calculator uses standard SI units: Force in Newtons (N), Distance in meters (m), Time in seconds (s), Work in Joules (J), and Power in Watts (W).
Q: Can I calculate kinetic energy with this tool?
A: This calculator focuses on mechanical work and power. For kinetic energy (KE = ½mv²), you would need a different calculator that includes mass and velocity.
Q: Is this tool completely free to use?
A: Yes, this is a 100% free online tool with no registration required. You can use it as much as you need for educational, personal, or professional purposes.
