Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...
Solve two Atwood machine problems step by step, including the effects of friction and an inclined plane. Learn how to set up free-body diagrams, apply Newton’s laws, and avoid common mistakes in ...
In this video, we break down the classic physics problem of a block on an incline with friction. Learn how to calculate the forces at play, including gravitational force, normal force, and frictional ...
In today's episode, Shini tells us about Static and Kinetic friction. Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it ...
I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...
Humans have been making fire using friction for thousands of years, with evidence of its use found in archaeological records across different cultures worldwide. Fire by friction is a testament to ...
Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...
Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in wet ...
Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...
