The first thing to note is that it is not just drivers who experience G-force. We all do, daily. When an object speeds up, slows down or switches direction, G-forces are created.
Ever noticed that sensation when braking while driving, being in an airplane during take-off and landing, or that feeling you get when going up and down on a rollercoaster? That is G-force.
Our bodies are designed to withstand these everyday forces, but from a driver's perspective, those feelings will be heightened in an F1 car, most notably when cornering, braking, or accelerating.
In the instance of a corner, drivers are exposed to lateral G-forces which push them towards the side of the car. These are also known as side-to-side G-forces.
The number of Gs refers to the weight of force that a driver will feel.
