1. What is the Work Equation?

The work equation in physics calculates the amount of energy transferred by a force acting through a distance. It's defined as the product of the force, the displacement, and the cosine of the angle between the force and displacement vectors.

2. How Does the Calculator Work?

The calculator uses the work equation:

Where:

• \( W \) — Work done (Joules)
• \( F \) — Force applied (Newtons)
• \( d \) — Displacement (meters)
• \( \theta \) — Angle between force and displacement vectors (degrees)

Explanation: The equation accounts for both the magnitude of force and displacement, as well as their directional relationship.

3. Importance of Work Calculation

Details: Calculating work is fundamental in physics for understanding energy transfer in mechanical systems, from simple machines to complex engineering applications.

4. Using the Calculator

Tips: Enter force in Newtons, distance in meters, and angle in degrees (0° means force and displacement are parallel, 90° means they're perpendicular).

5. Frequently Asked Questions (FAQ)

Q1: What are the units of work?
A: The SI unit of work is the Joule (J), which equals 1 Newton-meter (N·m).

Q2: When is work considered to be zero?
A: Work is zero when the force is perpendicular to displacement (θ=90°), or when there's no displacement.

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

Q4: Can work be negative?
A: Yes, when the force component is opposite to displacement (90° < θ ≤ 180°), work is negative.

Q5: How does this relate to kinetic energy?
A: The work-energy theorem states that the net work done equals the change in kinetic energy.
