1. What is Net Force?

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

Purpose: It helps determine 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 the forces you input to determine the net force acting on an object.

3. Importance of Net Force Calculation

Details: Calculating net force is essential for understanding an object's acceleration (using F=ma) and predicting its motion.

4. Using the Calculator

Tips: Enter all forces separated by commas. Positive values typically represent forces in one direction, negative values in the 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 the net force is zero?
A: A zero net force means the object is in equilibrium (either at rest or moving with constant velocity).

Q3: How does this relate to Newton's Second Law?
A: Net force is directly related to acceleration through F=ma (Force = mass × acceleration).

Q4: Can I use different units?
A: The calculator uses Newtons (N). Convert other units to Newtons before inputting.

Q5: How many forces can I input?
A: You can input as many forces as needed, separated by commas.
