Let's analyze each of the scenarios you provided to classify them as physical changes, chemical changes, or no change:
1. **Exhaust from a rocket as it leaves the ground**: This involves the combustion of fuel, which is a chemical reaction that produces gases. Therefore, this is a **chemical change**.
2. **Two bumper cars collide and move away from each other**: This is a result of a physical interaction where the bumper cars change their positions and momentum upon collision but do not undergo any change in their chemical composition. Thus, this is a **physical change**.
3. **Two swings on a playground hit each other and one swing moves away**: Similar to the bumper cars, when the swings collide, they change their positions, but there is no change in their chemical composition. This is another example of a **physical change**.
4. **Baseball player hits a ball and the bat shatters**: In this case, the bat breaking is a change in its physical structure, but it still remains a piece of wood (or composite material). There is no alteration in the chemical composition of the materials involved; thus, it is a **physical change**.
To summarize:
