1. What is Force Resolution in Physics?

Definition: Force resolution is the process of breaking down a single force into its horizontal and vertical components.

Purpose: This technique is essential for analyzing forces acting at angles in mechanics problems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F_x \) — Horizontal component (Newtons, N)
• \( F \) — Original force (Newtons, N)
• \( \theta \) — Angle from horizontal (degrees)

Explanation: The cosine function extracts the horizontal portion of the force vector based on its angle.

3. Importance of Force Resolution

Details: Resolving forces is fundamental in physics for analyzing equilibrium, motion, and structural stability in engineering applications.

4. Using the Calculator

Tips: Enter the force magnitude in Newtons and the angle from horizontal (0-90 degrees). The calculator will determine the horizontal component.

5. Frequently Asked Questions (FAQ)

Q1: What about the vertical component?
A: The vertical component is calculated using \( F_y = F \sin(\theta) \). This calculator focuses on the horizontal component.

Q2: Why is angle limited to 0-90 degrees?
A: In GCSE physics, angles are typically measured from the horizontal. For angles beyond 90°, trigonometric identities can be used.

Q3: What units should I use?
A: Force in Newtons (N) and angle in degrees. The result will be in Newtons.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise. Any inaccuracies would come from measurement errors in force or angle.

Q5: Can I use this for multiple forces?
A: This calculates one component at a time. For multiple forces, resolve each separately then combine components.
