Definition Of Force Of Gravity In Physics
Force of gravity synonyms force of gravity pronunciation force of gravity translation english dictionary definition of force of gravity.
Definition of force of gravity in physics. It is by far the weakest force known in nature and thus plays no role in determining the internal properties of everyday matter. Contact forces can be classified according to six types. Calculate the force of gravity on a 10 kg mass if it were 6 4 x 10 6 m above earth s surface that is if it were 2 earth radii from earth s center. Even though it is the weakest force gravity holds together the entire solar systems and galaxies.
Gravity definition the force of attraction by which terrestrial bodies tend to fall toward the center of the earth. In an object composed of many particles every particle interacts with every particle of the other object since we know that forces including gravity are vector quantities we can view these forces as having components in the parallel and perpendicular directions of the two objects in some objects such as spheres of uniform density the perpendicular components of force. Gravity is the weakest of the four known fundamental forces of nature yet it is the most dominant force. Center of gravity.
Gravity in mechanics the universal force of attraction acting between all matter. It can also be represented by the symbol f. Define force of gravity. Despite being all pervasive and important for keeping our feet.
Yet it also controls the trajectories of bodies in the universe and the structure of the whole cosmos. The unit of force within the international system of units si it can also be represented by the symbol n. The mass has units of kg whereas the weight is a force and has units of n. Gravity is the weakest of the four fundamental interactions of physics approximately 10 38 times weaker than the strong interaction 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.
Gravity is one of the four fundamental forces in the universe alongside electromagnetism and the strong and weak nuclear forces.
