1. What is the Work Equation?

The work equation (W = F × d) calculates the work done when a constant 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 equation:

Where:

• \( W \) — Work done (J)
• \( F \) — Force applied (N)
• \( d \) — Distance moved (m)

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

3. Importance of Work Calculation

Details: Calculating work is fundamental in physics and engineering to understand energy transfer, mechanical systems, and efficiency of machines.

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 are the units of work?
A: The SI unit is joules (J), which equals newton-meters (N·m). Other units include foot-pounds and ergs.

Q2: Does the angle between force and displacement matter?
A: Yes, for angles other than 0°, use W = F × d × cos(θ). This calculator assumes θ = 0°.

Q3: What's the difference between work and energy?
A: Work is the transfer of energy. Both share the same units, but work specifically refers to energy transferred by force.

Q4: Can this calculate work for variable forces?
A: No, this calculator is for constant forces only. Variable forces require integration.

Q5: What's a practical example of this calculation?
A: Lifting a 10 N weight vertically by 2 m requires 20 J of work (neglecting acceleration).
