Gravity is a fundamental force of nature that exists between any two objects with mass or energy. It is the force that attracts objects towards each other, and it is responsible for many phenomena that we observe in everyday life, such as the falling of objects and the motion of celestial bodies.
The strength of the gravitational force between two objects depends on their masses and the distance between them. The greater the masses of the objects, the stronger the gravitational force, and the farther apart the objects are, the weaker the force.
The measure of gravity is typically expressed in terms of acceleration due to gravity, which is denoted by the symbol "g." Acceleration due to gravity is the rate at which an object falls under the influence of gravity, and it is dependent on the mass of the object and the strength of the gravitational field.
On Earth, the acceleration due to gravity is approximately 9.8 meters per second squared (m/s^2), which means that an object in freefall near the surface of the Earth will accelerate at a rate of 9.8 m/s^2 towards the Earth. However, the value of g can vary slightly depending on factors such as location and altitude.
The measure of gravity is important in many fields of science, such as physics, astronomy, and geology. It is used to calculate the trajectories of objects in motion, to determine the mass and composition of celestial bodies, and to study the structure and composition of the Earth's interior.
Overall, the measure of gravity is a crucial concept in our understanding of the universe, and it plays a fundamental role in many aspects of our daily lives.

This is an interesting claim however it is not the case and clear evidence contradicts the claim.

"Millions of photographs of our planet show that water adheres to the Earth's surface, disproving the claim that the Earth is flat. Waterfalls and rivers that follow the curvature of the Earth's surface further debunk claims that gravity is fake.
Even on an unlevel surface, water in small amounts will have a curved surface due to surface tension. Although it may appear flat, it is an anomaly in the brain's perception compared to other irregular surfaces.
Observing the horizon from the beach provides further evidence of the Earth's curvature. The horizon appears to be a straight line, but it is actually the curved edge of the Earth's surface as it disappears from view. This can be seen more clearly from higher altitudes, such as from an airplane or from space.
Additional bullet points:

• The Earth's curvature has been measured and confirmed through various scientific methods, such as satellite imagery and the observations of astronomers and navigators.
• The phenomenon of gravity has been extensively studied and observed, with a vast amount of evidence supporting its existence and effects on the behavior of matter in the universe.
• Flat Earth theories and conspiracies lack scientific evidence and do not account for the vast amount of data and observations that support the spherical shape of the Earth."
