1. What is Work in Physics?

In physics, work is defined as the product of force and displacement in the direction of the force. It measures energy transfer when an object is moved over a distance by an external force.

2. How Does the Calculator Work?

The calculator uses the work equation:

Where:

• \( W \) — Work done (Joules)
• \( F \) — Force applied (Newtons)
• \( d \) — Displacement (meters)

Explanation: Work is done when a force causes displacement. No work is done if there's no displacement, regardless of the force applied.

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 and distance in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: Is work a scalar or vector quantity?
A: Work is a scalar quantity - it has magnitude but no direction.

Q3: What's the difference between work and energy?
A: Work is the transfer of energy, so both have the same units. Work done equals energy transferred.

Q4: When is work considered negative?
A: Work is negative when the force opposes the displacement (like friction doing negative work).

Q5: Does this calculator account for angle between force and displacement?
A: No, this calculates only for cases where force and displacement are in the same direction.
