Gravity is the mutual attraction of two bodies in the universe. Since gravity refers to an invisible force pulling matter together, there are many examples of gravity. Every single thing has gravity, including people. Some objects have much more gravity than others. The Earth, for example, has more gravity than people.
Then, what is gravity by Brainly?
Gravity is the force of attraction exerted by the earth towards its center on a body or an object. Without regular physical activity, the body slowly loses its strength, stamina and ability to function well. The greater the weight of an object, the greater the influence of gravity upon it.
Hereof, what is gravity in physics number?
The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.
What is gravity kid definition?
Gravity is a force of attraction that pulls together all matter (anything you can physically touch). The more matter something has, the greater the force of its gravity. That means really big objects like planets and stars have a stronger gravitational pull.
What is gravity short answer?
The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
Why is gravity?
Einstein suggested that the shape of spacetime is what gives rise to the force we experience as gravity. A concentration of mass (or energy), such as the Earth or sun, bends space around it like a rock bends the flow of a river.
