Understand what the area under a force-extension graph represents and calculate work done and elastic energy from linear or nonlinear curves.

A clear guide to bungee jumping physics, including free fall, elastic energy, changing forces and a worked Hooke's Law model.

Explore the physics of basketball projectile motion, including launch angle, speed, release height and shot trajectory.

Struggling with solving projectile motion problems on your physics exams? Tracking angles, heights, and velocities all at once can quickly get overwhelming. The secret to mastering 2D kinematics is splitting your data into independent horizontal and vertical components. Read our step-by-step guide to break down the essential equations and test your skills using our free interactive simulator!

Mastering CIE 9702 Paper 5 requires moving beyond simple plotting to precise uncertainty analysis. While Question 1 tests your experimental design, Question 2 demands mathematical rigor. You must draw a Worst Acceptable Line (WAL)—the steepest or shallowest gradient passing through all error bars—to quantify your gradient uncertainty. To simplify this, use our Line of Best Fit Graph Maker to instantly verify your manual WAL and intercept calculations against exam standards.
