1. When a meteoroid collides with the moon, surface material at the impact site melts. Explain Why?
2. A falling rock gains momentum as its speed increases. Does this observation contradict the law of conservation of momentum? Explain your answer.
The Attempt at a Solution
1. An object receiving an impulse from a smaller force has a final impulse larger then an object receiving an impulse from a larger force.
2. Because of the extreme surface to surface energy transfer, thermal energy is created melting the surface at the impact site.
