Newton's third law
In the vacuum of frictionless space, no force is needed to keep the ball moving. According to Newton's First Law of Motion, an object in motion will stay in motion unless acted upon by an external force. Therefore, once the ball is launched into frictionless space, it will continue moving indefinitely.
Rockets follow Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When a rocket engine expels hot gases at high speeds, the force of the gases pushing downward is met with an equal and opposite reaction force that propels the rocket upward. This allows rockets to generate thrust and lift off into space.
Rockets in space will continue to travel at the same speed and direction when their engines are turned off due to the principle of inertia, which states that an object in motion will remain in motion unless acted on by an external force. In the vacuum of space, there is very little to slow down the rocket's movement, so it will keep moving at a constant velocity until it encounters another force, such as gravity from a celestial body.
Newton's laws of motion apply to rockets by explaining how propulsion, thrust, and control are necessary for a rocket to accelerate and navigate through space. The third law states that for every action, there is an equal and opposite reaction, which is the principle behind rocket propulsion. Rockets work by expelling mass in one direction to create an equal and opposite force that propels the rocket in the opposite direction.
Yes, space is relative in terms of the movement of celestial bodies. This is described by Einstein's theory of relativity, which explains how the motion of objects in space is influenced by the curvature of spacetime caused by massive objects like planets and stars.
Newton's third law explains how rockets are launched into space.

Thousands if not millions. Not only are there space rockets, but also rockets used in research and war.
Surely at least thousands ARE launched everyday, if you include weapons and fireworks. But perhaps you are only interested in rockets that go into space.
Only 3 countries have launched a rocket and sent astronauts in to space. The United States, China, and Russia. Many other countries have sent astronauts in to space but they went on rockets belonging to other countries.
Yes, rockets are vehicles that can carry humans into space. Crewed spacecraft such as the SpaceX Crew Dragon and the Russian Soyuz spacecraft are launched into space atop rockets like the Falcon 9 and Soyuz rockets. Once in space, these spacecraft can dock with the International Space Station or travel to other destinations in space.
The first successful rockets built to go into space were ICBMs: the Soviet Sputnik I & II were launched on military ICBMs, the US Mercury spacecraft were launched on military ICBMs (Redstone & Atlas), the US Gemini spacecraft were launched on military ICBMs (Titan II). IIRC, the Delta & Saturn rockets were the first successful rockets built to go into space that didn't begin as military ICBMs. Although most Deltas are launched from Vandenberg AFB. The European Arian was the first commercial rocket built to go into space.
Korea is not launching rockets at the US. North Korea just launched a satellite on a rocket into space.
In United States, rockets are launch from Cape Canavral, Florida, at John F Kennedy Space Center.
The space shuttle is a reusable spacecraft that can launch like a rocket but can also land like an airplane. Rockets are typically one-time use vehicles that are not designed to return to Earth intact. Additionally, the space shuttle can carry astronauts and cargo to space, whereas rockets are mainly used for payload delivery.
