AI Thread Summary
The discussion questions the application of Newton's Laws of Motion in everyday scenarios, specifically focusing on car crashes, fatigue from rolling dough, and wear on airport runways. It argues that the smaller car skidding backwards more than the larger one does not accurately illustrate the third law. The fatigue experienced by the grandmother while rolling dough is debated in relation to the second law. Additionally, the dark lines on airport runways are examined concerning the first law, with participants expressing skepticism about these examples. Overall, the thread emphasizes the need for clarity in understanding and applying Newton's laws to real-life situations.

When 2 cars crash into the other, the smaller one skids backwards more than the larger one. - third law?

Grandmother is very tired after rolling the bread dough on her kitchen table.- second law?

After a while, airport runways show evidence of dark lines as tires are worn down from constant arrivals- first law?

Can you explain why you think those are the correct answers?
 
I think these are not correct examples for Newton's laws of motion.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
