1. What is a G-Force?

Definition: G-force is a measurement of acceleration relative to Earth's gravity. 1G equals the normal pull of gravity (9.81 m/s²).

Purpose: It helps quantify forces experienced by objects or people during acceleration, deceleration, or circular motion.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — G-force (dimensionless)
• \( a \) — Measured acceleration (m/s²)
• \( g \) — Standard gravity (9.81 m/s²)

Explanation: The formula compares any acceleration to Earth's gravitational acceleration.

3. Importance of G-Force Calculation

Details: Understanding G-forces is crucial in physics, engineering, aviation, space travel, and automotive safety.

4. Using the Calculator

Tips: Enter the measured acceleration in m/s² and gravity value (default 9.81 m/s²). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What does 1G feel like?
A: 1G is the normal force we experience standing on Earth's surface. It's equivalent to Earth's gravitational pull.

Q2: What's a typical G-force humans can withstand?
A: Most people can tolerate 4-6G briefly. Fighter pilots can handle up to 9G with special suits.

Q3: When would I use a different gravity value?
A: For calculations on other planets (e.g., 3.71 m/s² for Mars) or in different gravitational fields.

Q4: Is G-force always vertical?
A: No, G-forces can act in any direction depending on the acceleration vector.

Q5: How does G-force relate to weight?
A: At 2G, you'd feel twice as heavy as normal; at 0G (freefall), you'd feel weightless.
