1. What is the Weight Formula?

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

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 local gravitational acceleration.

3. Importance of Weight Calculation

Details: Calculating weight is fundamental in physics and engineering for understanding forces, designing structures, and solving problems related to gravity and motion.

4. Using the Calculator

Tips: Enter mass in kilograms and gravitational acceleration in m/s². On Earth, standard gravity is approximately 9.81 m/s².

5. Frequently Asked Questions (FAQ)

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

Q2: Why does weight vary on different planets?
A: Weight changes because gravitational acceleration (g) differs on other celestial bodies, while mass remains constant.

Q3: What is standard Earth gravity?
A: Standard gravity on Earth is approximately 9.80665 m/s², often rounded to 9.81 m/s² for calculations.

Q4: How does altitude affect weight?
A: Weight decreases slightly with increasing altitude because gravitational force weakens with distance from Earth's center.

Q5: Can weight be zero?
A: Yes, in freefall or orbit where there's no normal force opposing gravity, objects experience weightlessness.
