SUMMARY

G load, or gravitational load, quantifies acceleration in terms of the acceleration due to gravity (9.8 m/s²). It is calculated by dividing the actual acceleration by 9.8 m/s². For instance, an acceleration of 19.6 m/s² corresponds to 2 g's, indicating that the force experienced is double that of Earth's gravity. Understanding G load is crucial for fields such as aerospace and automotive engineering where acceleration forces are significant.

PREREQUISITES
  • Basic physics concepts, specifically Newton's laws of motion
  • Understanding of acceleration and force
  • Familiarity with gravitational acceleration (9.8 m/s²)
  • Knowledge of units of measurement in physics
NEXT STEPS
  • Research the effects of G load on human physiology in aerospace contexts
  • Explore the calculation of G forces in vehicle dynamics
  • Learn about the applications of G load measurements in crash testing
  • Investigate the role of G load in designing safety equipment for high-speed vehicles
USEFUL FOR

Aerospace engineers, automotive engineers, physicists, and anyone involved in fields requiring an understanding of acceleration forces and their effects on objects and humans.

Good evening,

Can anyone explain me G load? What is that (for now) in simple words? -0.5g? 2.0g? 2.5g?

Thanks a lot,
TBF

If a body is experiencing an acceleration, then the acceleration of the body can be expressed in g's. The acceleration in g's is equal to the actual acceleration divided by the acceleration of gravity (9.8 m/s2). The net force on the body is sometimes also expressed in g's. A force of 1 g is the amount of force needed to accelerate it at 9.8 m/s2.

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
