1. What is Net Force?

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).

2. How Does the Calculator Work?

The calculator uses the net force equation:

Where:

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

Explanation: Forces in the same direction are added, while opposite forces are subtracted.

3. Importance of Net Force Calculation

Details: Calculating net force is essential for understanding motion, predicting acceleration, and solving physics problems involving multiple forces.

4. Using the Calculator

Tips: Enter at least one force value. You can add up to three forces and specify if they act in the same or opposite directions.

5. Frequently Asked Questions (FAQ)

Q1: What if forces act at angles?
A: This calculator handles only parallel forces. For angled forces, vector components must be calculated first.

Q2: What units should I use?
A: The calculator uses Newtons (N). Make sure all inputs are in the same unit.

Q3: Can I calculate net force with more than 3 forces?
A: This calculator handles up to 3 forces. For more complex systems, you'd need to sum all forces algebraically.

Q4: What does a negative net force mean?
A: A negative result indicates the net force acts in the opposite direction of your reference direction.

Q5: How is net force related to acceleration?
A: According to Newton's second law: \( a = F_{net}/m \), where m is the object's mass.
