6.9 Rolling Down a Ramp – Energy Breakdown for IB Physics

Why does a rolling object accelerate differently than a sliding one? In this video, we break down the physics of rolling motion on a ramp — including gravitational potential energy, translational and rotational kinetic energy, and the role of moment of inertia. Topics Covered: PE = mgh and energy conversion KE = ½mv² + ½Iω² explained Rolling vs sliding dynamics Common IB exam misconceptions Perfect for: IB Physics SL/HL students Paper 1 and Paper 2 prep Question for You: Which part of rolling motion confuses you most — energy breakdown or torque? Comment below: ----- What’s the trickiest part of rotational energy for you?
