Detailed explanation-1: -Everything in the Universe is in motion because forces exist in the Universe. The gravitational force and the electromagnetic force ensure large objects are in motion while the weak and strong nuclear forces ensure the quantum world is constantly in motion. If there were no forces, there would be no motion.
Detailed explanation-2: -All matter in the universe is constantly in motion, from the revolution of Earth around the Sun to electrons moving around the nucleus of an atom.
Detailed explanation-3: -Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
Detailed explanation-4: -If we see with respect to earth then not all things are not in constant motion. But our earth itself is not stationary, it revolves around the sun. This means we all are revolving around the sun with the same velocity as that of the earth.
Detailed explanation-5: -Objects in space follow the laws or rules of physics, just like objects on Earth do. Things in space have inertia. That is, they travel in a straight line unless there is a force that makes them stop or change. The movement of things in space is influenced by gravity.
