Q: What is the main difference between classical and quantum mechanics?
Solution: The main difference is that classical mechanics is deterministic, while quantum mechanics incorporates probability.
Steps: 5
Step 1: Understand that classical mechanics deals with large objects, like cars and planets, and predicts their movements exactly.
Step 2: Realize that in classical mechanics, if you know the starting conditions (like position and speed), you can predict where an object will be in the future.
Step 3: Now, look at quantum mechanics, which deals with very tiny particles, like atoms and electrons.
Step 4: In quantum mechanics, you cannot predict exactly where a particle will be; instead, you can only calculate the probability of finding it in a certain place.
Step 5: So, the main difference is that classical mechanics is about certainty (deterministic), while quantum mechanics is about uncertainty (probabilistic).
