Physics of a Rollover

It’s all about the Gs baby. No, we’re not talking about the rap song by Big Bang. We’re talking about the measurement of gravitational forces acting on objects such as the human body.

At launch for example, the Space Shuttle astronauts experienced 1.7 Gs.

In a rally car rollover, such as the one Lauchlin O’Sullivan and Scott Putnam endured at the Oregon Trail Rally, they experienced 2 Gs, and for a brief time, exponentially more than that.

There is in fact a mathematical formula to measure this combo platter of G-forces, kinetic energy and violent speed changes the two Rally America competitors and their Subaru were subjected to.
