In the picture
- The incoming space rock: a small, solid meteoroid.
- The compressed air in front: a bright, hot cap of gas.
- The glowing trail behind: hot gas and dust left in its path.
- The separated fragments: pieces breaking off the rock.
Examples
- Rubbing your hands together makes them warm.
- A ball flying through the air slows down little by little.
Key takeaways
- Air pushes against fast-moving objects and slows them down.
- The lost motion becomes heat, so the object glows and can break apart.
