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 ...

Learn how to predict a ball’s landing distance from a ramp with clear, step-by-step physics explanations! ⚙️ This tutorial covers the principles of projectile motion, ramp angles, initial velocity, ...

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 ...

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 ...

One of the dirty little secrets of physics is that there is no generally accepted explanation of the basic laws of friction. An advance in the theory of cracks will stimulate fresh thinking on the ...

Avoid common pitfalls when calculating work done by friction! This video highlights the most frequent mistakes students make, from misinterpreting frictional forces to applying formulas incorrectly.

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 ...
