    Dimension Time
AI Thread Summary
Time is widely recognized as the fourth dimension in scientific theories, particularly in the context of spacetime. The concept of spacetime integrates time with the three spatial dimensions, fundamentally altering our understanding of physics. Resources like Wikipedia provide foundational knowledge on this topic, including discussions on higher dimensions. The application of these theories often arises in advanced physics, such as in relativity and cosmology. Understanding these concepts can enhance comprehension of the universe's structure and behavior.

i came across this article that says time is considered the 4 dimension(i think) and check up on wikipedia but doesn't know what they are talking about.so does anyone know where i can read up on this or better explain to me? :rolleyes:
 
Physics news on Phys.org
wow cool thx! i found another link which talks about higher dimension but don't understand a word after the 4th dimension...so i after hearing all those stuff,i was wondering when do u apply these?

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
