1. What is a Mass Calculator?

Definition: This calculator determines the mass of an object based on the force acting upon it and its acceleration using Newton's second law of motion.

Purpose: It helps students, physicists, and engineers calculate mass when force and acceleration are known.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( m \) — Mass (kilograms, kg)
• \( F \) — Force (Newtons, N)
• \( a \) — Acceleration (meters per second squared, m/s²)

Explanation: The force acting on an object is divided by its acceleration to determine its mass.

3. Importance of Mass Calculation

Details: Accurate mass calculation is fundamental in physics, engineering, and various scientific applications including motion analysis and structural design.

4. Using the Calculator

Tips: Enter the force in Newtons and acceleration in m/s² (default 9.81 for Earth's gravity). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: The calculator uses SI units - Newtons for force, m/s² for acceleration, and outputs mass in kilograms.

Q2: Why is the default acceleration 9.81 m/s²?
A: This is the standard acceleration due to gravity on Earth's surface.

Q3: Can I use this for objects in space?
A: Yes, but you'll need to input the actual acceleration, not Earth's gravity.

Q4: How precise are the results?
A: Results are precise to 3 decimal places, but actual precision depends on your input values.

Q5: What if I know mass and want to find force?
A: Rearrange the formula to F = m × a and use our Force Calculator.
