1. What is the Weight Formula?

The weight formula (W = m × g) calculates the force of gravity acting on an object's mass. Weight is measured in newtons (N) and represents the gravitational force exerted on an object.

2. How Does the Calculator Work?

The calculator uses the weight formula:

Where:

• \( W \) — Weight (newtons)
• \( m \) — Mass (kilograms)
• \( g \) — Gravitational acceleration (m/s²)

Explanation: The formula calculates the gravitational force acting on an object based on its mass and the gravitational acceleration at that location.

3. Importance of Weight Calculation

Details: Calculating weight is fundamental in physics and engineering for understanding forces, structural design, and various applications in mechanics and dynamics.

4. Using the Calculator

Tips: Enter mass in kilograms and gravitational acceleration in m/s². Standard Earth gravity is 9.8 m/s², but this can vary on different celestial bodies.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between mass and weight?
A: Mass is the amount of matter in an object (constant), while weight is the force of gravity acting on that mass (varies with location).

Q2: Why is g = 9.8 m/s² on Earth?
A: This is the average gravitational acceleration at Earth's surface, though it varies slightly depending on altitude and latitude.

Q3: How does weight change on different planets?
A: Weight changes with different gravitational accelerations, while mass remains constant. For example, on Mars (g = 3.7 m/s²), objects weigh less.

Q4: What are the SI units for weight?
A: Weight is measured in newtons (N) in the SI system, where 1 N = 1 kg·m/s².

Q5: Can weight be negative?
A: No, weight is always a positive value since both mass and gravitational acceleration are positive quantities.
