What is gravity? Gravity is a force pulling together all matter (which is anything you can physically touch). The more matter, the more gravity, so things that have a lot of matter such as planets and moons and stars pull more strongly.
Mass is how we measure the amount of matter in something.
The more massive something is, the more of a gravitational pull it exerts. As we walk on the surface of the Earth, it pulls on us, and we pull back.But since the Earth is so much more massive than we are, the pull from us is not strong enough to move the Earth, while the pull from the Earth can make us fall flat on our faces. In addition to depending on the amount of mass, gravity also depends on how far you are from something. This is why we are stuck to the surface of the Earth instead of being pulled off into the Sun, which has many more times the gravity of the Earth. Gravity is a very important and critical ay lives and you probably don’t even notice.
Here are some things that gravity does for us evey: Gravity brings us back down to the ground when we jump up. It stops us from floWhat is the importance of gravity? * ating into space. * Gravity keeps our food on our plates and our drinks in our glasses. * Gravity keeps the Earth in orbit around the sun and keeps us warm. It is the universal force of attraction that acts between all bodies that have mass. Though it is the weakest of the four known forces, it shapes the structure and evolution of stars, galaxies, and the entire universe.The laws of gravity describe the trajectories of bodies in the solar system and the motion of objects on Earth, where all bodies experience a downward gravitational force exerted by Earth’s mass, the force experienced as weight.
Isaac Newton was the first to develop a quantitative theory of gravitation, holding that the force of attraction between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them. Albert Einstein proposed a whole new concept of gravitation, involving the four-dimensional continuum of space-time which is curved by the presence of matter.In his general theory of relativity, he showed that a body undergoing uniform acceleration is indistinguishable from one that is stationary in a gravitational field. * Gravity also keeps the water on the Earth, the inhabitants on Earth, and the Earth’s atmosphere in its place. Gravity Welcome to Gravity Benefits Most companies spend a significant amount of money on employee benefits, but those employee and health benefit programs are commonly underutilized and improperly structured for maximum results.Growing a company and managing employees and benefits solutions can leave little time to orchestrate the optimum employee and health benefit solution. Gravity Benefits experience and different approach guides businesses in making smart choices about their: * Health Benefits * Wellness Benefits * Retirement Benefits * Executive Benefit Programs * Individual Health and Life Insurance Plans * pulls rain and snow down to our rivers.
What is the Use of Gravity? The obvious answer is that gravity helps to keep everything on the ground.In addition it: * keeps planets and moon in their orbits * causes tides in the ocean * collects material to form planets and suns * powers the fusion processes in stars * provides potential energy to run tubines at power plants * lets things dall “down” * bends light * provides direction for seeds to grow “up” * helps you balance * lets pendulums keep time History of gravitational theory Scientific revolution Modern work on gravitational theory began with the work of Galileo Galilei in the late 16th and early 17th centuries.In his famous (though possibly apocryphal) experiment dropping balls from the Tower of Pisa, and later with careful measurements of balls rolling down inclines, Galileo showed that gravitation accelerates all objects at the same rate. This was a major departure from Aristotle’s belief that heavier objects accelerate faster.  Galileo correctly postulated air resistance as the reason that lighter objects may fall more slowly in an atmosphere. Galileo’s work set the stage for the formulation of Newton’s theory of gravity.
