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 ...

Learn how tension and friction interact when an object moves at constant velocity. This video breaks down the force balance, explains why acceleration is zero, and shows how physics principles apply ...

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 ...

Moiré pattern evolution. Courtesy: Andrea Silva and Xin Cao. If you’ve ever struggled to shift a heavy piece of furniture, you have probably noticed that rotating the furniture while pushing it makes ...

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 ...

Say we consider a simple experiment of balancing a wooden rod on two fingers. The finger on the left, (1), will remain stationary, whereas the finger on the right, (2), will be moved toward the left.

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 ...

Quick, out behind the bike shed, Professors Pendry and Leonhardt are having a fight over a completely hypothetical situation. If we hurry, we should catch the end of round three. Science: it is ...
