Has gravity been proven as a force?

Most everyone in the scientific community believe gravitational waves exist, but no one has ever proved it. That’s because the signals from gravitational waves are usually incredibly weak.

How can you prove gravity is not a force?

In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line.

What is the force of gravity between me and the earth?

The force of Earth’s gravity is the result of the planets mass and density – 5.97237 × 1024 kg (1.31668×1025 lbs) and 5.514 g/cm3, respectively. This results in Earth having a gravitational strength of 9.8 m/s² close to the surface (also known as 1 g), which naturally decreases the farther away one is from the surface.

What kind of force is the force of gravity?

force of attraction
Gravity or gravitational force is the force of attraction between any two objects in the universe. The force of attraction depends on the mass of the object and the square of the distance between them. It is by far the weakest known force in nature.

Which force is responsible for sea tides?

Gravity
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).

What did Galileo do to experiment with gravity?

This generally means that the experiments they performed were fairly simple in nature. Galileo’s gravity experiments were no exception. By rolling different balls down a ramp from various heights, he was able to discover that the length the ball rolled was directly proportional to the square of the time taken.

What was the Cavendish experiment?

Cavendish experiment. The Cavendish experiment, performed in 1797–1798 by British scientist Henry Cavendish , was the first experiment to measure the force of gravity between masses in the laboratory and the first to yield accurate values for the gravitational constant.

How do you calculate gravitational constant?

First,determine the mass of the larger object In many cases,the larger object is a body like a planet or celestial body.
