What is a short definition of gravity?
gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
What is gravity short answer?
Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Gravity is what gives you weight. It is the force that pulls on all of the mass in your body.
What is the full meaning of gravity?
1 : a force of attraction that tends to draw particles or bodies together. 2 : the attraction of bodies by the force of gravity toward the center of the earth. 3 : great seriousness.
What is ment by gravity?
1 : a force manifested by acceleration toward each other of two free material particles or bodies or of radiant-energy quanta : gravity sense 3a(2) 2 : the action or process of gravitating. Other Words from gravitation Example Sentences Learn More About gravitation.
What is gravity Class 8 Ncert?
Every object that has mass exerts a gravitational pull or force on every other mass. The strength of this pull depends on the masses of objects at play. Hence, we define gravity as: Gravity is a force that attracts a body towards the centre of the earth, or towards any other physical body having mass.
What is gravity and why?
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. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight.
What word is gravity?
noun, plural grav·i·ties. the force of attraction by which terrestrial bodies tend to fall toward the center of the earth. heaviness or weight. gravitation in general. acceleration of gravity.
What is difference between gravity and gravitational?
Gravitation is the force acting between two bodies While, gravity is the force between an object and the earth’s surface.
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 English?

How is the literacy rate of a country defined?
Definition The literacy rate is defined by the percentage of the population of a given age group that can read and write. The adult literacy rate corresponds to ages 15 and above, the youth literacy rate to ages 15 to 24, and the elderly to ages 65 and above.
What do you mean by center of gravity?
1 : weight sense 1 —used chiefly in the phrase center of gravity. 2a : the gravitational attraction of the mass of the earth, the moon, or a planet for bodies at or near its surface broadly : gravitation. b : acceleration of gravity.
What is the value of the gravitational force?
It has a value of 6.6726 x 10 -11 m 3 kg -1 s -2. The effect of gravity extends from each object out into space in all directions, and for an infinite distance. However, the strength of the gravitational force reduces quickly with distance.
