Why Isn't "Zero G" the Same as "Zero Gravity"?

The video explains the concept of Zero-G, often misunderstood as zero gravity, highlighting that gravity exists everywhere. It introduces G-force, a unit of acceleration caused by gravity, and explains standard gravity as 9.8 m/s². The video describes how G-force is experienced as a sensation of weight in scenarios like spacecraft or dragster acceleration. It also clarifies that astronauts in space experience Zero-G due to constant freefall, despite being under gravity's influence.

What is standard gravity, and how is it measured?

How does the sensation of weight change in a spacecraft compared to being on Earth?
