Sir, I have a question: We understand that atoms constitute the entire universe. However, I'm curious about how is atom are created how it formed. It seems that no one can definitively state that atoms cannot be created, as they are perpetually present throughout our universe. Could you kindly provide a detailed explanation for this? This question has been intriguing me since my 9th class, and I would greatly appreciate your response.

Sir I study in class 11. But when I read a topic Friction in Force and Newtons Laws of Motion, I came across a question:- What is the direction of friction while a man is walking on a road? I am also confused by different answer from different sources . Although I couldn't get satisfactory conclusion to the question. I wil be very very Thankful to you if you answer to my question.

What's Friction? It's simply the force exerted between two surfaces to resist or oppose the relative motion between them given that they are in contact,so it's direction is always opposite to the motion happening between the two surfaces.
