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 ...

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 to calculate the coefficient of friction on inclined planes in this physics tutorial. Step-by-step explanations cover the forces, equations, and reasoning you need to solve friction problems ...

Explore the dynamics of mass tipping with springs and friction in this detailed physics analysis! This video demonstrates how forces, torque, and friction interact to influence tipping behavior, using ...

Really, this is the experiment I wanted to start on. How does friction work in Bad Piggies? Let me start with a quick summary of my experiments so far. Scale. For the size of stuff in Bad Piggies, I ...

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...

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 ...

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 ...
