Respuesta :
The force that contributed to the formation of planets, determines the motion of bodies in the solar system, and pulls objects to the center of Earth is called GRAVITY! The principle that states that an object at rest will stay at rest and that an object in motion will stay in motion is the law of INERTIA!
Gravity and Law of inertia or Newton's 1st law of motion are the answers for both questions.
Gravity is the force that contributed to the formation of planets, the motion of bodies in the solar system, and pulls objects towards the center of Earth. With the help of gravity, all activities that is necessary for our survival occurs on the planet earth.
Law of inertia or Newton's 1st law of motion which states that an object at rest will stay at rest and that an object in motion will stay in motion until an external force is applied on it. This law applies in the space where there is no external force that disturbs the state of an object i..e rest or motion so we can conclude that the law of inertia is that principle which about rest and motion.
