| Gravity |
If a heavy body is located in the vicinity of a planet, an observer at a fixed distance of the planet will measure an acceleration of the object directed towards the central area of this planet, if the object is not subject to the effect of other forces. On the surface of Earth, the acceleration caused by gravity is 9.80665 m / s², approximately.
The term "gravity" is also used to designate the gravitational phenomenon on the surface of planets or satellites. Isaac Newton was the first to state that the very nature is the force that makes objects fall with constant acceleration on Earth (terrestrial gravity) and the moving force that keeps the planets and stars. This idea led him to formulate the first general theory of gravitation, the universality of the phenomenon, expressed in his work Philosophiae Naturalis Principia Mathematica.

| Beetle |
Order Coleoptera have more species than any orders, covering almost 25% of all known forms of animal life. Approximately forty percent of all insect species have terdeskripsi are beetles (about 400,000 species), and new species are often found. Most major taxonomic family, Curculionidae, also included in this Order.
The spread of the beetle is very broad. Beetles can be found in all major habitats, except in the oceans and polar regions. They interact with the ecosystem in a variety of ways. Some species of beetle is a producer of detritus, by destroying the tissues of animals and plants die, scavengers certain types, and feed on garbage. Some species feed on fungi. Some species are flower and fruit eaters. There are also species that are parasites or parasitoids. Several other species are predators for other invertebrates. Many species of predator beetle is an important pest control agriculture. For example, in the family Coccinellidae beetles that prey on aphids, scale insects, thrips, and other plant-sucking insects that can cause damage to crops.
