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 according to Newton's Second Law (F=ma).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: All forces are added together (considering direction) to find the resultant force.

3. Importance of Net Force Calculation

Details: Calculating net force is essential for predicting an object's acceleration, understanding equilibrium situations, and solving physics problems.

4. Using the Calculator

Tips: Enter at least one force value. You can add up to three forces in this calculator. Positive values typically represent forces in one direction, negative values the opposite direction.

5. Frequently Asked Questions (FAQ)

Q1: How do I account for direction in force calculations?
A: Use positive values for one direction and negative values for the opposite direction.

Q2: What if I have more than three forces?
A: Calculate the sum of additional forces separately and include them in one of the input fields.

Q3: What does a net force of zero mean?
A: It means the forces are balanced and the object will remain at rest or continue moving at constant velocity (Newton's First Law).

Q4: How is net force related to acceleration?
A: According to F=ma, net force equals mass times acceleration. Divide net force by mass to find acceleration.

Q5: What units should I use?
A: This calculator uses Newtons (N), the SI unit for force. 1 N = 1 kg·m/s².
