Master tension and pullies: A Level Physics secrets explained

In this second video of my "Mastering Vectors" mini-series, we tackle one of the trickier ideas in A-level Physics — tension — using a real exam-style pulley question.

You’ll learn:
⚙️ Why the tension is the same all the way along a single wire
🎯 How to analyze forces on a pulley using components
📐 Why the x- and y-components of tension behave differently
💡 And how to calculate the resultant tension step-by-step

By the end you’ll be ready for the next challenge: forces on a slope.
