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 ...

Explore the physics behind driving on the Wall of Death and discover how centripetal force, friction, speed, and circular motion work together to keep a vehicle from falling. This video breaks down ...

Many NHL players like Connor McDavid and Nathan MacKinnon skate faster than 20 miles per hour every game. Hall of Famer Bobby ...

Learn how to calculate the force required to push a cart at constant velocity. This video explains the physics behind balanced forces, friction, and Newton’s First Law, showing why constant speed ...

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 ...

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 ...

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 ...

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 ...

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, ...

Today is the first day of second grade for SteelyKid, and yesterday I took her and her brother, The Pip, to the outdoor pool for an end-of-summer swim. While loading them into the car on the way home, ...
