1. What is the Work Done Equation?

Definition: This equation calculates the work done when a force moves an object over a distance at an angle.

Purpose: It helps in physics and engineering to determine the energy transferred by a force acting on an object.

2. How Does the Equation Work?

The equation is:

Where:

• \( W \) — Work done (Joules, J)
• \( F \) — Force applied (Newtons, N)
• \( d \) — Distance moved (meters, m)
• \( \theta \) — Angle between force and displacement (degrees)

Explanation: Only the component of force in the direction of displacement does work. The cosine term accounts for the angle between force and displacement.

3. Importance of Work Calculation

Details: Calculating work helps understand energy requirements, mechanical efficiency, and system performance in various applications.

4. Using the Calculator

Tips: Enter the force in Newtons, distance in meters, and angle in degrees (0° when force and displacement are parallel).

5. Frequently Asked Questions (FAQ)

Q1: What does θ = 0° mean?
A: It means the force is applied in the same direction as the displacement (maximum work done).

Q2: What if θ = 90°?
A: No work is done as the force is perpendicular to the displacement (cos(90°) = 0).

Q3: What are typical force values?
A: It varies greatly - from fractions of Newtons (small objects) to thousands of Newtons (machinery).

Q4: Why is work measured in Joules?
A: 1 Joule = 1 Newton-meter, the standard unit for energy and work in the SI system.

Q5: Does this include friction?
A: No, this is the work done by the applied force only. Friction would require additional calculations.
