Bookmark or Share- Gravity | Definition, Physics, & Facts | Britannicagravity, in mechanics, the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. On the other hand, through its long reach and universal action, it controls the trajectories of bodies in the solar system and ...
- Introduction to Newton's law of gravitation - Khan AcademyGravity is a force of mutual attraction between two objects that both have mass or energy. Newton's universal law of gravitation can be used to approximate the strength of gravitation forces between two objects as a function of the objects' masses and the distance between them. Created by Sal Khan.
- Newton’s law of universal gravitation (article) | Khan AcademyNewton’s law of universal gravitation describes objects falling down as well as objects in a circular orbit, such as a satellite orbiting Earth. How to find gravitational field strength. All objects attract other objects by producing a gravitational field g , which is defined as gravitational force per unit mass.
- Newton’s law of gravitation | Definition, Formula, & FactsNewton’s law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. Isaac Newton put forward the law in 1687.
