Answer on Mechanics | Relativity Question for mahi
it is easier to to pull a roller than to push it .why?
When moving horizontally, friction is an issue. When you pull a heavy object towards you, your pulling tends to bring the object up off the ground, which reduces friction that in turn reduces the effort required. However, when you push a heavy object away, the object stays on the ground (you are usually pushing downwards or horizontally, and rarely upwards), maximizing friction that in turn increases the effort required.
I'm extremely satisfied with your work. Excellent quality. Always.
Just have a question. Do you also provide help in understanding a concept? Not an assignment but for my learning. If certain concepts in the book are not clear, can you provide a simplified explanation of it using math that's understandable? You can charge the equivalent of an assignment.
Some things in the chapter attachments I sent you are not clear. They do not have much solved examples either.
Thanks a lot,
