1. What is Mass?

Mass is a fundamental property of physical objects that measures their resistance to acceleration when a force is applied. It is typically measured in kilograms (kg).

2. How Does the Calculator Work?

The calculator uses Newton's second law of motion:

Where:

• \( Mass \) — Measured in kilograms (kg)
• \( Force \) — Measured in newtons (N)
• \( Acceleration \) — Measured in meters per second squared (m/s²)

Explanation: The greater the force applied to an object, the more it accelerates, but the more mass it has, the less it accelerates for the same force.

3. Importance of Mass Calculation

Details: Calculating mass is essential in physics, engineering, and many practical applications like vehicle design, structural engineering, and space exploration.

4. Using the Calculator

Tips: Enter force in newtons (N) and acceleration in m/s². All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between mass and weight?
A: Mass is an intrinsic property of matter, while weight is the force exerted on mass by gravity.

Q2: What are typical units for mass?
A: The SI unit is kilograms (kg), but grams (g) and pounds (lb) are also commonly used.

Q3: How does mass relate to inertia?
A: Mass is a measure of an object's inertia - its resistance to changes in motion.

Q4: Can mass be negative?
A: No, mass is always a positive quantity in classical physics.

Q5: How is mass different in relativity?
A: In relativity, mass can appear to increase with velocity, but rest mass remains constant.
