A stupid question? No, a very good question.
First, the word and concept particle is drawn from our macro sensory experience and is not useful in describing micro quantum phenomena. Perhaps, we should make up and use a word like 'quanticle' to eliminate the confusion created by the use of...
A_B,
Congratulations on finding the text for which you were looking.
Here is an idea from Norbert Wiener that you may find interesting. All that physicists really know are the results of measurements of experiments, and the measurements of initial conditions and of the resulting conditions...
All of Drakkith's replies are correct. You can trust him.
Physics theories are successful to the extent that they accurately predict a diversity of observed phenomena, and if they are not falsified by other observations. Classical E&M was mostly successful in the 19th century, predicting what...
My guess is that you are a student in a first course in mechanics. Is my guess is correct? If my guess is correct, are you truly confused about kinetic energy or are you just having fun at the expense of the responders? If you are truly confused, I will try to explain work and energy.
Any measurement of one of a pair changes its state and therefore the state of the other. This is the FTL transmission of information. Unfortunately, it isn't all that useful, because the prior state of the second member wasn't known.
It is to be noted that we both have avoided using the word...

Would you please provide a more detailed response to "How do you define PARTICLE?"
