1. What is Net Force?

Net force is the vector sum of all forces acting on an object. According to Newton's second law of motion, the net force acting on an object is equal to the mass of the object multiplied by its acceleration.

2. How Does the Calculator Work?

The calculator uses the fundamental equation of motion:

Where:

• \( F \) — Net force (Newtons)
• \( m \) — Mass of the object (kilograms)
• \( a \) — Acceleration of the object (meters per second squared)

Explanation: This equation shows the direct proportionality between force and acceleration when mass is constant.

3. Importance of Net Force Calculation

Details: Calculating net force is essential in physics and engineering for understanding motion, designing structures, and solving dynamics problems.

4. Using the Calculator

Tips: Enter mass in kilograms and acceleration in meters per second squared. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of net force?
A: The SI unit of force is the Newton (N), where 1 N = 1 kg·m/s².

Q2: How does net force relate to motion?
A: A non-zero net force causes acceleration in the direction of the force, while zero net force means constant velocity (or rest).

Q3: What's the difference between net force and individual forces?
A: Net force is the combined effect of all forces acting on an object, considering both magnitude and direction.

Q4: Can this calculator be used for rotational motion?
A: No, this calculates linear force. For rotational motion, you need to consider torque (τ = I × α).

Q5: How does mass affect net force?
A: For a given acceleration, greater mass requires greater force. Mass is a measure of an object's resistance to acceleration.
