Well I can give you one example of the use of gravity. A roller coaster, a mechanical winch pulls the cars up to a high spot and then gravity takes you on the rest of your ride.
Your question is a little vague message me and we can clarify on this.

∙ 7y agoEvery planetary body, including the Earth, is surrounded by its own gravitational field, which exerts an attractive force on all objects. Assuming a spherically symmetrical planet (a reasonable approximation), the strength of this field at any given point is proportional to the planetary body's mass and inversely proportional to the square of the distance from the centre of the body.
The strength of the gravitational field is numerically equal to the acceleration of objects under its influence, and its value at the Earth's surface, denoted g, is approximately 9.8 m/s². This means that, ignoring air resistance, an object falling freely near the earth's surface increases in speed by 9.8 m/s (32 ft/s or 22 mi/h) for each second of its descent. Thus, an object starting from rest will attain a speed of 9.8 m/s (32 ft/s) after one second, 19.6 m/s (64 ft/s) after two seconds, and so on. According to Newton's 3rd Law, the Earth itself experiences an equal and opposite force to that acting on the falling object, meaning that the Earth also accelerates towards the object. However, because the mass of the Earth is huge, the acceleration of the Earth by this same force is negligible, when measured relative to the system's center of mass.

Why is gravity a good choice of force to use for measuring the shear strength of different materials?
I think its because gravity is all around us. Materials are used to make structures and buildings, which will house valuable things. Which means the materials used will have to be able to take the gravity and the elements that are thrown at them.
Who first developed the calendar used most today?
Romans first developed the calendar used most today
What is paper used for today?
paper is used for writing on and can also be used for oragamy
What is specific gravity?
Specific gravity, usually referred to as relative density is the ratio of the mass of a given volume of a substance to the density of a different reference substance. Water is often used as the reference.
What is lactometerfor what purpose and in what industry is the lactometer used?
lactometer is one kind of hydrometer used to determined the purity as well as specific gravity of milk
How is gravity used in gymnastics?
Gravity is not "used". In gymnastics, gymnasts almost defy-gravity by flipping in the air but have no control of what gravity does.
Which major force did isaac newton discover that allways affects us today?
Isaac Newton discovered the force of gravity, which continues to influence and affect us today.
Why do you still have religion today?
That is like asking why do we have still have gravity today. Truth is not a popularity contest.
What is the relative gravity on earth?
"Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such. So, you would have to specify, "specific gravity [or density] of what substance"."Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such.

nothing
How did water fountains work before electricity?
With gravity. Peter the Great put extensive fountains in his Peterhoff castle and all of them worked by gravity. They are still working today. The ancient Romans used a combination of aqueducts, underground cisterns, and gravity to bring water to their fountains and cities. These too are still working in many places.
How has gravity affacted you today?
Gravity has kept me in my chair today. This has made it immeasurably easier to do my work. Gravity has also been instrumental in keeping a plentiful supply of atmosphere conveniently located in my proximity. I in turn have persisted in breathing, rhythmically and steadily as far as I know, all of which has undoubtedly had a salutary influence on my overall performance.
Does gravity act on aeroplanes?
Gravity acts against aeroplanes and forward speed and lift are used to conquer gravity.
How is gravity used in a sentence?
Earth has gravity rather than other planets.
How magnatism electricity gravity is in earth?
Your question is ambiguous. Are you asking why gravity exists or is gravity or more to the point can Gravity/Magnetism be used as an energy source.

How is the gravity survey caried out today?
The gravity survey is carried out with the use of a gravimeter, which uses a fixed length spring and mass attached to a calibration spring.
