The velocity of a meteor rock fragment falling on Neptune is calculated using the formula v = √(2gh), where v is the velocity, g is the gravitational acceleration on Neptune, and h is the height from which the fragment falls. This formula assumes that there is no air resistance.
The gravitational acceleration on Neptune is approximately 11.15 m/s². This is significantly higher than the gravitational acceleration on Earth, which is 9.8 m/s².
The mass of the meteor rock fragment does not significantly affect its velocity as long as the same formula is used. This is because the mass of an object does not affect its acceleration due to gravity.
Yes, the velocity of a meteor rock fragment falling on Neptune can be affected by air resistance. However, since Neptune has a very thin atmosphere, the effect of air resistance is minimal and can be ignored for most calculations.
Yes, there is a maximum velocity that a meteor rock fragment can reach while falling on Neptune. This is known as the terminal velocity, which is the maximum velocity an object can reach when the force of air resistance is equal to the force of gravity. However, since the atmosphere on Neptune is so thin, the terminal velocity for a meteor rock fragment is much higher than on Earth.
