--- title: Gravity — a lesson of Mova's school · trees and pragmatics description: «Gravity», a lesson of the world course of Mova's primary school, sentence by sentence with dependency trees and pragmatics. It begins: Gravity is a pull that every object has on every other object; the more matter (mass) something has, the stronger it pulls. --- [Mova](https://md.mova.elamur.ai/free/en/) · [this page in HTML](https://mova.elamur.ai/free/en/corpora/school/world/6-gravity/) [home](https://md.mova.elamur.ai/free/en/) / [corpora](https://md.mova.elamur.ai/free/en/corpora/) / [school](https://md.mova.elamur.ai/free/en/corpora/school/) / [World](https://md.mova.elamur.ai/free/en/corpora/school/world/) / Gravity # Gravity Lesson 6 of the world course of Mova's primary school: 17 sentences, each with its syntax tree and pragmatics.

How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/world/6-gravity/). - [0](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/0/) — Gravity is a pull that every object has on every other object; the more matter (mass) something has, the stronger it pulls. - [2](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/2/) — The Moon is falling towards the Earth all the time, but it also moves sideways so fast that it keeps missing: like a ball whirled on a string, it goes round and round, with gravity as the string; if the string snapped, the ball would fly off in a straight line. - [3](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/3/) — In the same way the Sun's gravity keeps the Earth and the other planets going around it. - [4](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/4/) — Without air, a feather and a hammer fall equally fast: an astronaut tried it on the Moon, and both reached the ground together. - [5](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/5/) — Gravity is a pull between all objects that have mass. - [6](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/6/) — The more mass an object has, the stronger its gravity. - [7](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/7/) — Gravity gets weaker the farther apart two objects are. - [8](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/8/) — The Earth's gravity pulls everything towards the centre of the Earth. - [9](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/9/) — Weight is the pull of gravity on an object. - [10](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/10/) — The Earth's gravity keeps the Moon going around the Earth. - [11](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/11/) — The Sun's gravity keeps the planets going around the Sun. - [12](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/12/) — Without air, light and heavy objects fall at the same speed. - [13](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/13/) — A feather falls slowly on the Earth because the air pushes against it. - [14](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/14/) — Even in air, two small solid balls, one heavy and one light, dropped from a low height land almost together, because the air hardly slows them. - [15](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/15/) — Gravity also holds the air and the oceans to the Earth. - [16](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/16/) — The Moon's gravity pulls on the oceans and helps make the tides, the sea rising and falling along the shore about twice a day. - [17](https://md.mova.elamur.ai/free/en/corpora/school/world/6-gravity/17/) — Gravity works in space too; astronauts float because they are falling around the Earth together with their ship. - ← previous: [The Sun as a star and the stars](https://md.mova.elamur.ai/free/en/corpora/school/world/5-the-sun-and-the-stars/) - next →: [The shape and size of the Earth, the poles and the equator](https://md.mova.elamur.ai/free/en/corpora/school/world/7-shape-and-size-of-the-earth/) - ↑ back to [World](https://md.mova.elamur.ai/free/en/corpora/school/world/)
