Motion and gravity

The second box was bolted or nailed to the ground/flooring.

What did I win for answering the question (with out of the box thinking)?

Because she was tired from pushing the first box.

No, but really. The increased weight caused too much friction between the box and the floor.

This is a question about friction. You are going to want to learn about normal force.

Is this a homework question? If you take a shot at it you will give you feedback.

Wait a sec! You want him to give himself feedback? That's some tough teaching you got there. That's really meta advice!

It is also about "A body at rest tends to remain at rest."- Sir Issac Newton
(until a force is exerted against the body strong enough to overcome that tendency)

This is incorrect. Without friction any unbalanced force will cause a stationary object to start moving.

Well, yeah. If she put enough STP on the floor, she could blow the toy box with a straw.

My objection was to the predicate "strong enough to overcome" which is completely the wrong idea since any non-zero net force is "strong enough" to move a stationary object. That is what Newton's second law says; if there is a non-zero net force (of any strength) on an object, it accelerates.

I am pretty sure that the original question was from a homework about friction.

No, but really. I guess if there was a free-floating, stationary object in space, like a planet, and you dropped a leaf on it, then it might...Wait...Are you sure about that?

Yes, I am absolutely sure. I have a Physics degree and I taught Physics for a few years.

My statement is 100% correct. Any non-zero net force on a stationary object will cause it to move. That is true under any circumstance due to Newton's Second Law. Just to point out I used the term "net force" which means that you add the effects of all the forces acting on the object (i.e. friction can provide a force to cancel out your push).

Yes, if you drop a leaf on a planet, the planet accelerates. Of course the acceleration is extremely small... but if you agree that F=ma applies to planets and leafs than a force from a leaf will result in an acceleration of the planet.

I don't know if you want to work through the Physics, or if you are just idly arguing... if you do want me to work through the math with you, I will.

Well, give me an F, professor Blackboard.

By Newton's second law... if I give you an F it will result in an A.

Cool.
Really, I started giving you an example where your numbers would add up. I should get credit for that.
