Tentacles of an octopus as well limbs of a lizard are analogous structures.
Analogous structures or organs perform the same function in different organisms that bear no resemblance to each other anatomically. Analogous structures are formed as a result of convergent evolution, i.e. different structures evolving for the similar function and thus having similarity. Tentacles of an octopus as well as limbs of a lizard are used for the similar function, i.e. locomotion in this case.
On the other hand, homologous structures result from divergent evolution. Homologous organs contain a similar basic structure but perform distinct functions in different organisms.

Provide structure and support, facilitate growth through mitosis. allow passive and active transport, produce energy, create metabolic reactions, aids in reproductive.
I'm guessing the rocket scenario is the first one and the asteroid one is the last. That being said...
1) The fuel in the rocket provides it with the energy it needs to propel itself into space. The rocket throttles at the bottom, allow it to break free from the earth's gravity by pushing against the earth's greater mass.
2) If you are inside of the bus, in a fixed spot not moving, and the bus is moving. That means you are moving in the same direction as the bus. If it stops, you're still moving at the speed that it was once originally moving at. Obviously, since you weigh less than the bus you are going to fly forwards.
3) There is no gravity or friction in space, so items won't slow down no matter what. Even if an object such as a meteor is flung into space with the tiniest bit of force it will keep flying through space at a consistent speed, since there's nothing to slow it down... unless it hits something else.
4) Looking back at the previous answer, the asteroid is flying through space at a consistent speed (which is really fast). Suddenly it comes in close range to the moon which is bigger in size, and thus has a stronger gravitational pull, and pulls the asteroid into it's field.
