2 bumper cars collide and move away from each other

Question

Exhaust from rocket fuel as a spaceship leaves the ground
2 swings on the playground hit each other and one swing moves away
A baseball player hits a ball and the bat shatters

answer choices; chemical change, physical change, no change

Answer 1

Let's analyze each scenario to determine if they represent a chemical change, physical change, or no change:

1. 2 bumper cars collide and move away from each other: This is a physical change. The cars collide and change their motion, but their physical structure remains the same.

2. Exhaust from rocket fuel as a spaceship leaves the ground: This involves a chemical change. The rocket fuel undergoes a chemical reaction, burning and producing exhaust gases as it propels the spaceship.

3. 2 swings on the playground hit each other and one swing moves away: This is a physical change. Similar to the bumper cars, the swings change their position but do not undergo any change in their physical composition.

4. A baseball player hits a ball and the bat shatters: This is primarily a physical change. The bat breaking involves a change in its physical structure, but the materials themselves (wood, etc.) do not change chemically.

Summarizing:

1. Bumper cars collide: Physical change
2. Exhaust from rocket fuel: Chemical change
3. Swings hit each other: Physical change
4. Bat shatters: Physical change
