1. What is the Work Formula?

The work formula (W = F × d) calculates the amount of work done when a force moves an object over a distance. Work is measured in joules (J) in the International System of Units.

2. How Does the Calculator Work?

The calculator uses the work formula:

Where:

• \( W \) — Work done (in joules, J)
• \( F \) — Force applied (in newtons, N)
• \( d \) — Distance moved (in meters, m)

Explanation: Work is done when a force causes displacement. The formula assumes the force is constant and acts in the same direction as the displacement.

3. Importance of Work Calculation

Details: Calculating work is fundamental in physics and engineering to determine energy transfer, mechanical advantage, and system efficiency.

4. Using the Calculator

Tips: Enter force in newtons (N) and distance in meters (m). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of work?
A: The SI unit of work is the joule (J), which equals one newton-meter (N·m).

Q2: What if the force isn't parallel to displacement?
A: Use W = F × d × cos(θ) where θ is the angle between force and displacement.

Q3: Can work be negative?
A: Yes, when the force component opposes the displacement (like friction doing negative work).

Q4: How does this relate to energy?
A: Work equals the change in energy (Work-Energy Theorem: W = ΔKE).

Q5: What's the difference between work and power?
A: Work is energy transfer, while power is the rate of doing work (P = W/t).
