ELi5 : Please explain G-forxe in simple terms
In: 0
Accelerating in any direction causes you to feel a force, following the equation f = ma, where m is your mass.
You feel this force when you’re in a car accelerating, or in a train, or a rocket going up to space, wherever.
“G-force” is just measuring that force as a multiple of the force due to gravity. 1g is the force you feel pulling you to the ground. 2 g’s is twice as strong as that. 3 g’s is three times as strong. And so on.
It doesn’t mean the force you’re measuring is caused by gravity. When we say astronauts are experiencing 3 g’s during a rocket launch, that force is due to the rocket, not due to gravity. We’re just comparing its strength to the force from gravity.
