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 ...

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 ...

In this chapter, we’ll explore how to calculate the spring constant of a block on an incline! 🧲 Learn the step-by-step process to solve this problem and apply your knowledge of forces, friction, and ...

Learn the core mechanics behind pushing a block against a wall in this Physics 01 example. This short explains forces, friction, and equilibrium step by step, helping you build strong intuition for ...

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 ...
