1. What is the Mass Calculator?

Definition: This calculator determines the mass of an object using Newton's second law of motion (F = ma).

Purpose: It helps physics students and professionals calculate mass when force and acceleration are known.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( m \) — Mass (kilograms)
• \( F \) — Force (Newtons)
• \( a \) — Acceleration (m/s²)

Explanation: Mass is calculated by dividing the applied force by the resulting acceleration.

3. Importance of Mass Calculation

Details: Accurate mass calculations are essential in physics experiments, engineering designs, and various scientific applications.

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 is the standard value for Earth's gravity?
A: Approximately 9.81 m/s², though it varies slightly by location.

Q2: Can I use pounds for force?
A: First convert pounds-force to Newtons (1 lbf ≈ 4.448 N).

Q3: What if acceleration is zero?
A: The calculator requires acceleration > 0 (division by zero is undefined).

Q4: How precise should my inputs be?
A: Use 2-3 decimal places for typical applications, more for scientific work.

Q5: Does this account for relativistic effects?
A: No, this is classical Newtonian physics. For relativistic speeds, use E=mc².
