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 determine the net force acting on an object.

3. Importance of Net Force Calculation

Details: Understanding net force is crucial for analyzing motion according to Newton's Second Law (F=ma).

4. Using the Calculator

Tips: Enter up to three force values in Newtons. The calculator will sum them to find the net force.

5. Frequently Asked Questions (FAQ)

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

Q2: What if I have more than three forces?
A: You can combine some forces before input or modify the calculator to handle more inputs.

Q3: What units does this calculator use?
A: All forces should be in Newtons (N), the SI unit for force.

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

Q5: What if the net force is zero?
A: A zero net force means either no motion or constant velocity (no acceleration).
