AI Thread Summary
The discussion revolves around a homework question related to Newton's Second Law, specifically focusing on a crossword puzzle clue: "when you sit in a chair, it exerts ------------- against you." The answer, which is 11 characters long with the 6th character being 'L', is identified as "NORMAL FORCE." The explanation highlights that when a person sits in a chair, their body exerts a downward force due to gravity, and the chair responds with an equal and opposite force, known as the normal force. This interaction illustrates Newton's Third Law of Motion, emphasizing the balance of forces in a static situation. The poster expresses gratitude for any assistance and acknowledges a mistake in posting in the wrong section of the forum.

Ok. I'm talking with my girlfriend right now and her little boy is having problems with his homework. I can't figure it out and remembed this site being posted at at sitepointforums.com so I was hoping someone here could help. The homework consists of doing a crossword puzzle. She was able to help him with all of it, but one question. That question is:
when you sit in a chair, it excerts-------------against you.

It is supposed to be something from Newton's Second Law, and is 11 characters and the 6th character should be an L.

If anyone can lend a helping hand, I would be extremely greatful and I'm sure she will be too. I hope this type of post is ok. Thank you anyone for their knowledge and help.

Opps, I just saw the homework help section. Can someone move it there? sorry about that. Got so excited I finaly found a place to ask.

NORMAL FORCE.
Your body exerts a force on the chair. And we know that F=ma. If there is a force, there should be an acceleration, yet you sit put.
The chair exerts an equal and opposite force(called the normal force) on the person sitting in the chair.
Hope this helps besides giving you the answer.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
