What is gravity? 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. Earth's gravity is what keeps you on the ground and what causes objects to fall. Gravity is what holds the planets in orbit around the Sun and what keeps the Moon in orbit around Earth. The closer you are to an object, 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. 1  Javascript must be enabled to use Cool Cosmos.

What Is the Measure of the Force of Gravity on an Object? The weight of an object is the measure of the force of gravity on that object. The calculation of the weight of an object takes into account both the object's mass and gravitational force.

What is gravity? Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.

Gravity Gravity is the weakest of the four fundamental forces of physics, approximately 1038 times weaker than the strong force, 1036 times weaker than the electromagnetic force and 1029 times weaker than the weak force. As a consequence, it has no significant influence at the level of subatomic particles.

Gravity Gravity is the force which pull everything around us down towards the ground. Objects feel heavy because of the force of gravity on them. Isaac Newton realized that gravity is important not just for everyday objects around us, but also for the motion of planets and stars.

The Acceleration of Gravity It is known as the acceleration of gravity - the acceleration for any object moving under the sole influence of gravity. A matter of fact, this quantity known as the acceleration of gravity is such an important quantity that physicists have a special symbol to denote it - the symbol g.

Gravity: A Force of Attraction The answer is gravity. Gravity is a force of attraction between objects that is due to their masses. The force of gravity can change the motion of an object by changing its speed, direction, or both. In this section, you will learn about gravity and its effects on objects, such as astronauts in space.

What is Specific Gravity? - Definition, Formula, Calculation & Examples When the specific gravity is greater than one, the object will sink, and when the specific gravity is less than one, then the object will float. If the specific gravity is equal to one', this means that the object will neither sink nor float -- it will hover in the liquid.

- Gravity has a familiar physical meaning but also a nonphysical meaning—basically seriousness. Thus, something grave possesses gravity. You can refer to the gravity of a person's manner, though public figures today seem to have a lot less gravity than they used to have. Or you can talk about a grave situation, as in the example sentence.

Atom Fun facts about gravity. 1  Ocean tides are caused by the gravity of the moon. 2  Mars is smaller and has less mass than Earth. 3  The standard gravity from Earth is 1 g force.  At some point when falling, the friction from the air will equal the force of gravity and the object will be at a constant speed.

specific gravity The term specific gravity, symbolized sp gr, refers to the ratio of the density of a solid or liquid to the density of water at 4 degrees Celsius. The term can also refer to the ratio of the density of a gas to the density of dry air at standard temperature and pressure, although this specification is less often used. Specific gravity is a dimensionless quantity; that is, it is not expressed in units.

- Ask someone the meaning of the word down and they point toward the center of the Earth. Down is the direction of theforce of gravity.Gravity dependson massThe force of gravity depends on how much mass you have. If you have more mass,gravity pulls on you with more force.

Space Environment 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.

StarChild Question of the Month for February 2001 However, if we are to be honest, we do not know what gravity is in any fundamental way - we only know how it behaves. Here is what we do know... Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.
