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

2. How Does Net Force Calculation Work?

The calculator uses the formula:

Where:

• \( F_{net} \) — Net force (Newtons)
• \( F_i \) — Individual forces acting on the object (Newtons)

Explanation: All forces are added together. Forces in opposite directions should be subtracted (use negative values).

3. Importance of Net Force

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

4. Using the Calculator

Tips: Enter up to three forces. For opposite directions, use negative values. Leave unused fields blank.

5. Frequently Asked Questions (FAQ)

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

Q2: What if the net force is zero?
A: A zero net force means the object will maintain its current state of motion (Newton's First Law).

Q3: Can I add more than three forces?
A: This calculator handles up to three forces. For more complex situations, combine some forces before entering.

Q4: What units does this calculator use?
A: All calculations are in Newtons (N), the standard unit of force.

Q5: How is this related to acceleration?
A: According to F=ma, divide the net force by the object's mass to find its acceleration.
