Newton's laws allow us to find what happens to the stone when it is released into space

The first law determines that it goes in a straight line with constant velocity The third law states that the astronaut also receives a force of equal magnitude in the opposite direction to that applied to the stone.

Newton studied the relationship between forces and bodies, finding three mathematical relationships that describe this interaction:

The inertia law. Where it states that if there is no net force on a body, it is maintained with constant velocity in a straight line The second law. It says that the force is proportional to the product of the mass and the acceleration Action and reaction law. It states that all forces appear in pairs, one acting on each body with equal magnitude and opposite direction.

Let us apply these laws to the case of throwing a stone in space:

When the stone is in space and left the hand there is no net force on it, therefore it must continue with constant speed in a straight line

When it is still being released, according to the third law or of action and reaction, the hand exerts a force on the stone and the stone exerts a reaction on the most of equal magnitude, but in the opposite direction. Consequently, the astronaut also acquires a lower speed by having a much greater mass in the opposite direction of the stone.

In conclusion, using Newton's laws we can find out what happens to the stone when it is released into space.

Answer from: mauricio18s

The rock will continue to travel in a straight line with a constant velocity for ever... The reason is, once it leaves your hand there is no force acting on the rock, so it will just continue to move in a natural motion which is constant velocity.

Answer from: Quest

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
