1. What is Net Force?

Definition: Net force is the vector sum of all forces acting on an object.

Purpose: It determines the overall effect of multiple forces on an object's motion.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F_{net} \) — Net force (Newtons)
• \( F_i \) — Individual forces (Newtons)

Explanation: The calculator sums all input forces to find the resultant force acting on an object.

3. Importance of Net Force Calculation

Details: Calculating net force is fundamental in physics for predicting an object's acceleration according to Newton's Second Law (F = ma).

4. Using the Calculator

Tips: Enter at least one force value. You can add up to three forces in this calculator. All values should be in Newtons (N).

5. Frequently Asked Questions (FAQ)

Q1: How do I account for forces in different directions?
A: This calculator sums forces algebraically. For forces in opposite directions, use negative values.

Q2: What if I have more than three forces?
A: You can chain calculations - calculate the sum of three forces, then use that result as an input for additional forces.

Q3: What's the difference between net force and resultant force?
A: They are essentially the same concept - the overall effect of all forces acting on an object.

Q4: How does net force relate to acceleration?
A: According to Newton's Second Law: F_net = m × a, where m is mass and a is acceleration.

Q5: Can I use this for non-linear forces?
A: This calculator handles simple vector addition. For complex force systems, you'd need to consider vector components.
