1. What is Net Force?

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

Purpose: Understanding net force is fundamental in physics for analyzing motion and applying Newton's laws.

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 total net force acting on an object.

3. Importance of Net Force Calculation

Details: Calculating net force helps predict an object's acceleration (F=ma), determine equilibrium conditions, and solve dynamics problems.

4. Using the Calculator

Tips: Enter up to three forces in Newtons. The calculator will sum them to find the net force. For more forces, simply add the result to additional forces manually.

5. Frequently Asked Questions (FAQ)

Q1: How do I account for direction in net force calculations?
A: For opposite directions, use negative values (e.g., -10 N for leftward force if rightward is positive).

Q2: What if forces are at angles?
A: This calculator handles 1D forces only. For angled forces, resolve them into components first.

Q3: What does a net force of zero mean?
A: It means balanced forces (equilibrium) - the object will maintain its current motion state.

Q4: How is net force related to acceleration?
A: According to Newton's 2nd Law: F_net = m × a. Divide net force by mass to get acceleration.

Q5: Can I add more than three forces?
A: Yes, either calculate in stages or modify the code to include more input fields.
