1. What is the Work Done by a Constant Force?

Definition: Work is the energy transferred to or from an object via the application of force along a displacement.

Purpose: This calculator helps determine the work done when a constant force acts on an object causing displacement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: Work is calculated as the product of force and displacement in the direction of the force. When the force isn't parallel to displacement, only the component in the displacement direction contributes to work.

3. Importance of Work Calculation

Details: Calculating work helps understand energy transfer in mechanical systems, efficiency of machines, and power requirements.

4. Using the Calculator

Tips: Enter the force in Newtons, displacement in meters, and angle in degrees (0° for parallel force). All values must be positive (angle between 0-90°).

5. Frequently Asked Questions (FAQ)

Q1: What does θ = 0° mean?
A: The force is completely parallel to displacement (maximum work done).

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

Q3: What are typical Newton values?
A: 1 N ≈ the force of Earth's gravity on 102g mass. Human pushing force might be 50-500N.

Q4: Why is work in Joules?
A: Joule is the SI unit of energy, and work is energy transfer.

Q5: Can work be negative?
A: In this calculator, no (angle limited to 0-90°). In physics, work can be negative when force opposes displacement (θ > 90°).
