1. What is the Work Equation?

The work equation (W = F × s) calculates the amount of work done when a force causes a displacement. Work is measured in joules (J) in the International System of Units.

2. How Does the Calculator Work?

The calculator uses the work equation:

Where:

• \( W \) — Work done (joules)
• \( F \) — Force applied (newtons)
• \( s \) — Displacement (meters)

Explanation: Work is done when a force moves an object through a distance in the direction of the force.

3. Importance of Work Calculation

Details: Calculating work is fundamental in physics and engineering to determine energy transfer in mechanical systems.

4. Using the Calculator

Tips: Enter force in newtons (N) and displacement in meters (m). All 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: When is work considered zero?
A: Work is zero when there's no displacement or when the force is perpendicular to the displacement.

Q3: How is this different from power?
A: Power is the rate of doing work (work per unit time), measured in watts (W = J/s).

Q4: Can the work be negative?
A: Yes, when the force component is opposite to the displacement direction (e.g., friction slowing an object).

Q5: Does this equation apply to rotational work?
A: No, rotational work uses torque and angular displacement (W = τ × θ).
