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 Net Force Formula 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: Net force determines whether an object will accelerate, decelerate, or remain at constant velocity according to Newton's Second Law (F=ma).

4. Using the Calculator

Tips: Enter all forces separated by commas. Positive values typically represent forces in one direction, negative values represent opposite direction.

5. Frequently Asked Questions (FAQ)

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

Q2: What if forces are at angles?
A: This calculator assumes all forces are along the same line. For angled forces, you would need to break them into components first.

Q3: What does a zero net force mean?
A: The object will remain at rest or continue moving at constant velocity (Newton's First Law).

Q4: How is this different from balanced forces?
A: Balanced forces result in zero net force, while unbalanced forces produce a non-zero net force.

Q5: What units should I use?
A: The calculator uses Newtons (N), the SI unit for force.
