Can someone help me with the following 5 scenarios? You have to describe why/how they happen. (No links or answers that are clearly incorrect and please answer all of them.)
1. A comet in space continues to move without slowing down or slowing up.
2. A large asteroid crashes into the moon.
3. A rocket launches from Earth, leaves the atmosphere, and goes into space.
4. You are standing in a bus that suddenly stops and you keep moving/falling forward.
5. A small asteroid crashes into the moon.
