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 ...

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 ...

If you've spent any time traveling on highways in the United States, chances are that you've seen those strange-looking ramps off to the side of the road near large hills and steep inclines. They're ...

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 ...

To gain more confidence with FEA, it’s a good idea to first solve simple problems with pencil and paper. Many less-experienced users of finite-element-analysis (FEA) software often have no clue if the ...

A good old game of carrom has really stood the test of time. Set up a board and people around will flock to it while practising their finger gymnastics. You may not have noticed but the game often ...

Is friction real? Once, with the quiet certainty of someone who just stayed up all night in the company of equations describing concrete, my college roommate told me that friction was made up. Now, ...

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 ...

Introduction Have you ever driven up a mountain, seen a sign reading "Hazard! Icy Roads Ahead," and wondered why ice makes roads dangerous to drive on? The answer has to do with friction—specifically, ...
