Is there gravity in the process of falling body?

In summary, Galileo's experiments showed that the acceleration of a falling body is not affected by its mass, volume, or chemical elements. Newton and Einstein tried to explain this phenomenon with their theories of gravity, but neither were perfect. Newton's law of gravity also cannot explain certain phenomena, such as tides on both sides of a planet. This led to the need for a new time-space theory, which Einstein discovered with his principle of equivalence in his general theory of relativity. However, the reason for the equivalence between inertial and gravitational mass is still unknown.

Is there gravity in the process of falling body?

The answer is not.

Galileo demonstrated that the acceleration of falling body is not concerned with mass, volume and chemical elements. This is Galileo phenomenon. Newton and Einstein attempted to use their theory, gravity law or general relativity to explain Galileo phenomenon, but it is not perfect. All physics know this.

All physics also know that many phenomena can not clarified by Newton’s gravity law. For example, Newton’s law of gravity can only perfectly explain why tides occur on the side nearest to it, but not on the other side.

In fact, there is not necessary relation between the phenomenon of falling object and Newton’s law of gravity.

We need a new time-space theory.

424319,

Einstein preceded your thought experiment by 97 years.

This discovery (November 1907) is known as the "happiest moment" of Einstein's endeavors to understand the simplicity of nature.

The outcome is the Principle of Equivalence of his general theory of relativity.

The equivalence is the inertial mass as that found in Newton's 2nd law of motion and the gravitational mass in Newton's law of universal gravitation.

Until now nobody knows the reason why these masses should be equivalent. They are just found to be equivalent by Einstein. He did not gave any good explanation.
 

1. Is there gravity in the process of falling body?

Yes, gravity is present in the process of falling body. Gravity is the force that pulls objects towards the center of the Earth, and it is constantly acting on all objects, including falling bodies.

2. How does gravity affect a falling body?

Gravity causes a falling body to accelerate towards the ground. This is because gravity is a force that acts on the mass of an object, and the acceleration of an object is directly proportional to the force acting on it.

3. Does the mass of a falling body affect the force of gravity?

Yes, the mass of a falling body does affect the force of gravity. Objects with a greater mass will experience a greater force of gravity compared to objects with a smaller mass. This means that heavier objects will accelerate faster towards the ground when falling.

4. How does air resistance affect the process of falling body?

Air resistance is a force that opposes the motion of a falling body. As a falling body moves through the air, it experiences air resistance which slows it down. This means that air resistance can affect the speed at which a falling body accelerates towards the ground.

5. Can a falling body ever stop accelerating?

No, a falling body will continue to accelerate until it reaches its terminal velocity. Terminal velocity is when the force of air resistance on a falling body is equal to the force of gravity, resulting in a constant speed of descent. This means that the falling body will no longer accelerate and will continue to fall at a constant speed until it reaches the ground.
