G Force Formula:
From: | To: |
Definition: This calculator determines the G-force experienced during linear acceleration by comparing it to Earth's gravity.
Purpose: It helps engineers, pilots, and physics students understand the forces acting on objects or people during acceleration.
The calculator uses the formula:
Where:
Explanation: The formula compares any acceleration to Earth's gravitational acceleration, showing how many times stronger it is.
Details: Understanding G-forces is crucial for vehicle safety design, aerospace engineering, and human tolerance limits in acceleration scenarios.
Tips: Enter the linear acceleration in m/s² and gravity value (default 9.81 m/s² for Earth). Gravity must be > 0.
Q1: What does 1G represent?
A: 1G equals Earth's gravity (9.81 m/s²), which is the normal force we experience at rest on Earth's surface.
Q2: What's a typical G-force for car acceleration?
A: Most cars produce about 0.3-0.5G during normal acceleration, while performance cars may reach 0.8-1G.
Q3: When would I change the gravity value?
A: Use different values for other celestial bodies (e.g., 1.62 m/s² for Moon, 3.71 m/s² for Mars).
Q4: How does this relate to human tolerance?
A: Humans can tolerate about 5G briefly, 9G with training/suits, and 3G sustained for several minutes.
Q5: Is this different from rotational G-force?
A: Yes, this calculates linear G-force only. Rotational G-force requires additional angular velocity and radius inputs.
