1. What is Resultant Force?

Definition: The resultant force is the single force that represents the vector sum of all the individual forces acting on an object.

Purpose: It helps in analyzing the net effect of multiple forces acting on a body, simplifying complex force systems to a single equivalent force.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F_r \) — Resultant force (Newtons, N)
• \( F \) — Individual forces (Newtons, N)

Explanation: The calculator sums all the forces you input (comma separated) to find the resultant force.

3. Importance of Resultant Force Calculation

Details: Calculating resultant force is essential in physics and engineering to determine the net effect of multiple forces on an object's motion or equilibrium.

4. Using the Calculator

Tips: Enter all forces separated by commas (e.g., "10, 20, -5" for forces of 10N, 20N, and -5N). Negative values indicate opposite direction.

5. Frequently Asked Questions (FAQ)

Q1: What if forces act in different directions?
A: Use positive values for one direction and negative values for the opposite direction.

Q2: How do I represent forces at angles?
A: This calculator handles 1D forces. For angled forces, resolve them into components first.

Q3: What does a resultant force of zero mean?
A: It means all forces are balanced and the object is in equilibrium (not accelerating).

Q4: Can I use different units?
A: All forces must be in the same units (preferably Newtons) for accurate results.

Q5: How many forces can I input?
A: You can input as many forces as needed, separated by commas.
