1. What is Net Force?

Definition: Net force is the vector sum of all forces acting on an object. It determines the overall effect of multiple forces.

Purpose: Calculating net force helps predict an object's motion according to Newton's Second Law (F=ma).

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 forces you input. Positive values typically represent right/upward forces, negative values represent left/downward forces.

3. Importance of Net Force Calculation

Details: Understanding net force is crucial for solving physics problems related to motion, equilibrium, and dynamics.

4. Using the Calculator

Tips: Enter forces separated by commas (e.g., "10, -5, 3.2"). The calculator will sum all values to find net force.

5. Frequently Asked Questions (FAQ)

Q1: How do I represent force direction?
A: Use positive numbers for one direction (e.g., right) and negative for the opposite (e.g., left).

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

Q3: What does zero net force mean?
A: The object is in equilibrium (either at rest or moving with constant velocity).

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

Q5: Can I calculate net force from mass and acceleration?
A: Yes (F=ma), but this calculator sums individual forces directly.
