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.

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: Work is only done by the component of force in the direction of movement.

3. Importance of Work Calculation

Details: Understanding work done is fundamental in mechanics, energy transfer, and efficiency calculations.

4. Using the Calculator

Tips: Enter the force in Newtons, distance in meters, and angle in degrees (0° for parallel forces).

5. Frequently Asked Questions (FAQ)

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

Q2: What does θ = 90° mean?
A: The force is perpendicular to movement (no work done, cos(90°) = 0).

Q3: Can work be negative?
A: Yes, when 90° < θ ≤ 180°, indicating force opposes motion.

Q4: What's the unit of work?
A: Joules (J), equivalent to 1 Newton-meter.

Q5: How is this different from power?
A: Work is energy transfer, while power is the rate of work done (Joules/second = Watts).
