A positive feedback loop amplifies or increases the output of a system, leading to instability and often resulting in runaway behavior. In contrast, a negative feedback loop works to stabilize the system, by reducing the output and bringing it back towards a desired set point or equilibrium. Positive feedback loops are often seen in situations where rapid change or acceleration is needed, while negative feedback loops are more common in systems that require stability and regulation.
