1. What is Net Force?

Definition: Net force is the vector sum of all forces acting on an object. It determines the object's acceleration according to Newton's Second Law (F = ma).

Purpose: Calculating net force helps predict an object's motion and is fundamental in physics problem solving.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F_{net} \) — Net force (Newtons)
• \( F_1, F_2, F_3 \) — Individual forces (Newtons)

Explanation: All forces are added together (considering direction - positive/negative values for opposite directions).

3. Importance of Net Force Calculation

Details: Net force determines whether an object will accelerate, decelerate, or remain at constant velocity (if net force is zero).

4. Using the Calculator

Tips: Enter at least two forces (required). Use positive values for forces in one direction, negative for opposite direction. The third force is optional.

5. Frequently Asked Questions (FAQ)

Q1: How do I represent forces in opposite directions?
A: Use positive values for one direction and negative values for the opposite direction.

Q2: What if the net force is zero?
A: A zero net force means the object will maintain its current state of motion (Newton's First Law).

Q3: How does this relate to acceleration?
A: Net force equals mass times acceleration (F=ma). Divide net force by mass to find acceleration.

Q4: Can I add more than three forces?
A: This calculator handles up to three forces. For more, simply add them sequentially.

Q5: What units should I use?
A: Use Newtons (N) for all force values for consistent results.
