1. What is the Work Calculator?

Definition: This calculator computes the work done when a force acts on an object over a distance at an angle.

Purpose: It helps physics students and professionals calculate mechanical work in joules.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Work done (Joules)
• \( F \) — Force applied (Newtons)
• \( d \) — Distance moved (meters)
• \( \theta \) — Angle between force and direction of motion (degrees)

Explanation: Work is calculated as the product of force, distance, and the cosine of the angle between them.

3. Importance of Work Calculation

Details: Understanding work is fundamental in physics for analyzing energy transfer in mechanical systems.

4. Using the Calculator

Tips: Enter the force in newtons, distance in meters, and angle in degrees (0° for parallel, 90° for perpendicular).

5. Frequently Asked Questions (FAQ)

Q1: What does negative work mean?
A: Negative work occurs when the force component opposes the motion (angle between 90° and 270°).

Q2: What's the unit of work?
A: The SI unit is joules (J), equivalent to newton-meters (N·m).

Q3: When is work zero?
A: Work is zero when the force is perpendicular to motion (90°) or when no displacement occurs.

Q4: How does angle affect work?
A: Maximum work occurs at 0° (force parallel to motion), decreasing to zero at 90°.

Q5: Can this calculate kinetic energy?
A: The work-energy theorem states work equals change in kinetic energy, but this calculator only computes work.
