1. What is Work in Physics?

In physics, work is the energy transferred to or from an object via the application of force along a displacement. The basic formula is W = F × d, where W is work, F is force, and d is displacement.

2. How Does the Calculator Work?

The calculator uses the work equation:

Where:

• \( W \) — Work in joules (J)
• \( F \) — Force in newtons (N)
• \( d \) — Displacement in meters (m)

Explanation: Work is done when a force causes displacement. No work is done if there's force but no displacement.

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 and displacement in meters. 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), equivalent to newton-meters (N·m).

Q2: Is work a scalar or vector quantity?
A: Work is a scalar quantity, having magnitude but no direction.

Q3: What's the difference between work and power?
A: Work is energy transfer, while power is the rate of doing work (work per unit time).

Q4: Can work be negative?
A: Yes, when the force opposes the displacement (like friction doing negative work).

Q5: What if the force isn't parallel to displacement?
A: Then you must use W = F × d × cosθ, where θ is the angle between force and displacement vectors.
