1. What is Newton's Second Law of Motion?

Definition: Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Purpose: This fundamental physics principle helps calculate the force required to accelerate an object or determine acceleration from known forces.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F_{net} \) — Net force (Newtons, N)
• \( m \) — Mass of the object (kilograms, kg)
• \( a \) — Acceleration (meters per second squared, m/s²)

Explanation: The net force acting on an object equals the product of its mass and acceleration.

3. Importance of Net Force Calculation

Details: Understanding net force is crucial for solving problems in mechanics, engineering, vehicle design, and many other physics applications.

4. Using the Calculator

Tips: Enter the mass in kilograms and acceleration in m/s². All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the units for each variable?
A: Force in Newtons (N), mass in kilograms (kg), and acceleration in meters per second squared (m/s²).

Q2: Does this work for deceleration?
A: Yes, deceleration is simply negative acceleration. Enter the magnitude and consider direction separately.

Q3: How does this relate to weight?
A: Weight is the force of gravity on an object (F = m × g, where g = 9.81 m/s² on Earth).

Q4: What if multiple forces act on an object?
A: The calculator uses net force (sum of all forces). Calculate individual forces first if needed.

Q5: Can I calculate mass or acceleration instead?
A: Rearrange the formula: m = F/a or a = F/m. We may add these options in future versions.
