The Law of Perfect Timing + Newton's Laws of Motion

I'm pretty sure that this household was witness today to all 3 of Newton's Laws of Motion (at once).

Object 1: Monet (quite a solid mass, if I say so myself)

Object 2: Myself and office blinds (hurriedly goes on to object 3, avoiding subject of mass)

Object 3: Desk and standing folder holder

Newton's First Law of Motion = in order for the motion of an object to change, a force must act upon it.

Newton's Second Law of Motion = the relationship between acceleration, force, and mass.

Newton's Third Law of Motion = anytime a force acts from one object to another, there is an equal force acting back on the original object.

Let's add another law = The Law of Perfect Timing.

Here are the events:

1. Monet circles the desk, preparing to leap on the desk to jump to the window sill.

2. Angie, seeing this, grabs the window blind wand and begins to push the blinds open so Monet can more easily acquire her goal.

3. Monet, not seeing this, or maybe anticipating that the mama was faster, hurriedly jumps up to the window, colliding with the partially closed and open blinds. Perfect timing.

4. Monet, slamming into the blinds, falls backwards on the desk, scrambling for all of her worth (mass + motion) knocks standing folder holder (inert object) to the floor, strewing papers, files, and notes in all directions.

5. Angie, still in awe of the perfect timing and collision of all objects, quickly grabs the camera to document events.

Monet, surveying the damage.

Boys and girls, what did we learn today?

The motion of an object (Monet) changed when she hit the blinds. See 1st Law of Motion.

The relationship between acceleration (both Monet and mama), force (moving Monet), and mass (Monet, mama, and blinds) was apparent. See 2nd Law of Motion.

A force (Monet) acted upon two other objects - the blinds, which forced her back to the desk, and the file holder, which by merely being in the way knocked her off the desk and spewed paperwork hither and yon. See 3rd Law of Motion.

Great lesson. Class dismissed.
