1. What is G-Force from Speed?

Definition: This calculator determines the g-force experienced by an object moving in a circular path based on its velocity, turn radius, and gravity.

Purpose: It helps engineers, physicists, and motorsport professionals calculate centripetal acceleration in g-forces.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — G-force (multiples of gravity)
• \( v \) — Velocity (meters/second)
• \( g \) — Gravitational acceleration (9.81 m/s²)
• \( r \) — Radius of turn (meters)

Explanation: The square of velocity is divided by the product of gravity and radius to determine the g-force.

3. Importance of G-Force Calculation

Details: Understanding g-forces is crucial for designing safe roller coasters, race tracks, aircraft maneuvers, and understanding human tolerance limits.

4. Using the Calculator

Tips: Enter the velocity in m/s, turn radius in meters, and gravity (default 9.81 m/s²). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical g-force in everyday situations?
A: Normal gravity is 1G. Cars in turns might experience 0.5G, while fighter jets can pull 9G.

Q2: How does g-force affect the human body?
A: High g-forces can cause loss of consciousness (usually above 5G) or physical trauma at extreme levels.

Q3: What's the difference between positive and negative g-forces?
A: Positive G pushes you into your seat, negative G lifts you out (like on a roller coaster drop).

Q4: How do I convert km/h to m/s for this calculator?
A: Divide km/h by 3.6 (100 km/h = 27.78 m/s).

Q5: What's the highest g-force survived by a human?
A: Race car driver David Purley survived an estimated 179G deceleration in a 1977 crash (with severe injuries).
