    Anyone have any really good examples for Newton's 1st and 2nd Laws?

    How about:

    As you sit in your chair, you are not moving violently about the room. Now, start standing up. If you push up twice as hard, you accelerate twice as fast.

    Incredible, no?

    Here's a really good example of Newton's 3.law:
    Stick your finger in your nose. Notice that as the finger pushes on the nostril, the nostril squeezes back on the finger.
