Explain newtons first law when an object is at motion

what it basically states is than an object in motion will stay in motion until something stops it, whether that be the wind slowing it down, friction, a person, or a wall. For example - when you throw a ball, several forces are acting on it that stop it from going forever. Gravity is pulling the ball back to the ground and the wind/ air is pushing against it as well. Thats why if you throw a ball in space it will continue going forever since gravity and air arent acting on it .

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
