whether a stone thrown upword with very high speed fall to the same point to the ground?
If yes then why even the earth is in motion?
if the speed is high enough, the stone will in fact not fall back to the same spot, due to coriolis effect caused by the earth's rotation.
Under everyday conditions, the deflection is so small that it makes no practical difference, and the object appears to fall right back to where it started.
The stone thrown upward with high speed will not fall to the same point on the ground due to the motion of the Earth. This is because both the stone and the Earth are in motion.
When a stone is thrown upward, it experiences the force of gravity pulling it downward. However, it also has an initial upward velocity from the throw. This results in the stone moving upwards against the force of gravity until its velocity becomes zero at the highest point of its trajectory, known as the peak.
At this point, gravity starts to pull the stone back down towards the Earth, causing it to accelerate downwards. During this downward motion, the Earth is also rotating on its axis and revolving around the Sun. As a result, the ground below the stone moves slightly during the stone's descent.
Therefore, if the stone were to fall straight down to the same point on the ground, it would actually miss its target due to the Earth's rotation and revolution. The Earth's motion causes the point directly below the stone to change, so the stone will land slightly away from its original starting point.
In conclusion, the stone thrown upward with high speed will not fall to the same point on the ground because both the stone and the Earth are in motion.
