```text
class Car          ← ONE definition (the blueprint)
   │  fields: color, speed
   │  methods: accelerate()
   ▼
new Car("red")     ← many OBJECTS (instances), each with its own state

```python
class Car:
    def __init__(self, color):
        self.color = color      # per-instance state
        self.speed = 0
    def accelerate(self):
        self.speed += 10

a = Car("red")                  # object #1
b = Car("blue")                 # object #2 — independent state
a.accelerate()
print(a.speed, b.speed)         # 10 0  → separate instances
print(a.color is b.color)       # False → different objects
```
