1. What is G Force?

G-force is a measurement of the type of acceleration that causes a perception of weight. It's commonly experienced in vehicles, amusement park rides, and aerospace applications. The "G" stands for gravitational acceleration equivalent (9.81 m/s²).

2. How Does the Calculator Work?

The calculator uses the G force formula:

Where:

• \( G \) — G force (multiples of Earth's gravity)
• \( Speed \) — Velocity in meters per second (converted from mph)
• \( r \) — Radius of the turn in meters
• \( g \) — Acceleration due to gravity (9.81 m/s²)

Explanation: The formula calculates the centripetal acceleration experienced in circular motion, expressed as multiples of Earth's gravity.

3. Importance of G Force Calculation

Details: Understanding G forces is crucial for vehicle design, safety in amusement rides, pilot training, and understanding human tolerance to acceleration forces.

4. Using the Calculator

Tips: Enter speed in miles per hour (mph) and turn radius in meters. The calculator automatically converts mph to m/s and computes the resulting G force.

5. Frequently Asked Questions (FAQ)

Q1: How does speed affect G force?
A: G force increases with the square of speed - doubling speed quadruples the G force.

Q2: What's a typical G force in driving?
A: Normal turns might produce 0.2-0.5G, while racing can reach 1.5-2G. Most cars can't exceed 1G due to tire limits.

Q3: What G forces can humans tolerate?
A: Untrained people can handle about 5G briefly. Fighter pilots with training and suits can withstand 9G.

Q4: Why convert mph to m/s?
A: The formula uses SI units (meters and seconds) for consistency with the gravitational constant (9.81 m/s²).

Q5: How does radius affect G force?
A: Larger radius turns produce lower G forces at the same speed, as the turn is less sharp.
