Gravitational effects refer to the influence that mass has on the space around it, causing objects to be attracted towards one another. This phenomenon is most commonly observed with large bodies like Earth, the Moon, and the Sun. The strength of this attraction depends on the masses involved and the distance between them, as described by Newton's Law of Universal Gravitation. One of the most noticeable gravitational effects is the phenomenon of weight, which is the force exerted on an object due to Earth's gravity. Additionally, gravitational effects are responsible for the orbits of planets around the Sun and the tides in Earth's oceans, which are influenced by the gravitational pull of the Moon.
