1. What is Net Force?

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

Purpose: Calculating net force helps determine an object's acceleration 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 input forces to determine the total net force acting on an object.

3. Importance of Net Force Calculation

Details: Net force determines whether an object will accelerate, decelerate, or remain at constant velocity.

4. Using the Calculator

Tips: Enter at least one force value. You can add up to three forces in this calculator. Positive values typically represent forces in one direction, negative values represent opposite direction.

5. Frequently Asked Questions (FAQ)

Q1: What if forces act in different directions?
A: Use positive values for one direction and negative values for the opposite direction when entering forces.

Q2: How many forces can I calculate?
A: This calculator handles up to three forces, but net force can be calculated for any number of forces.

Q3: What units does this use?
A: All calculations are in Newtons (N), the SI unit for force.

Q4: What if my net force is zero?
A: A zero net force means balanced forces - the object will maintain its current state of motion (Newton's First Law).

Q5: How does this relate to acceleration?
A: According to F=ma, divide net force by mass (kg) to find acceleration (m/s²).
