Have you ever read relative velocity?You should read this before posting anything
Actually there is

Please read the link which i had posted firstHave you ever read relative velocity?
Which link?Please read the link which i had posted first
One question for you and for your PDF file.
I had the same view as you have regarding this topic until @Sneaker provided me that PDF file yesterday.If someone can prove this wrong,I am ready to change my opinion tooOne question for you and for PDF your file.
You traveling in train, train running at 100 Kmph ( constantly) ,you throw the ball in front seat of yours.
And now train stop, you again throw the ball in front seat .
Did the range changes? If yes please explain.
Then you should change, your pdf never consider that, when a missile launch, it already have velocity of earth, and the missile propulsion system add velocity in V0.I had the same view as you have regarding this topic until @Sneaker provided me that PDF file yesterday.If someone can prove this wrong,I am ready to change my opinion too
OK.I`ll confirm it with my teacherThen you should change, your pdf never consider that, when a missile launch, it already have velocity of earth, and the missile propulsion system add velocity in V0.
The difference here is that the train is enclosed hence no external force acts on the ball (whole flight takes place with the system). The distances and time involved are so small that you can't possibly determine any change in range. Even throwing speed varies. Another difference is that ball is a non-powered flight. Hence the question is at best rhetorical and doesn't have any substance in it. Compare it with a bowler now.. can he bowl the ball at same speed standing still and running from a distance?I had the same view as you have regarding this topic until @Sneaker provided me that PDF file yesterday.If someone can prove this wrong,I am ready to change my opinion too
Yes and no. There are 2 effects 1 is increasing the range (due to earth's momentum) and 2 Decreasing range (due to earth's rotation). However, I think increase in range is always smaller than decrease in range (due to losses frictional and other losses) in eastward launch. Exact amount will be based on so many factors...
I would be if there was no atmosphere and other losses. But that is not the case in actual world.
Sorry. You were dead wrong here. Ball does land in a different position for all practical purpose. But if you are making some assumption like 1. No horizontal velocity component (that is, perfectly vertical) 2. No air/atmosphere/external force/internal forces 3. Uniform gravity, then yes, it will fall on same spot because of inertia. But sadly, these conditions are not true for a missile launch. Newton's 3rd law says object will maintain state of rest or uniform motion "until external force act" on the object. Missile has it's own power which constitutes that external force (along with atmosphere and other factors).Incorrect. That would only be the case if there were no gravity and hence no initial inertial velocity of the missile before being launched. Take for example a perfect ball which you toss it perfectly vertical in the air. Does it fall a little to the east of its launching point? Or does it fall directly back on the spot from where it was launched? The answer obviously is 'b'.
So the case of a missile launch on Earth has to be seen in isolation, as if the earth was standing still since the relative velocity of the missile and the Earth before the launch is zero.
