Combined Translational and Rotational Motion | Pure Rolling | Acceleration & Kinetic Energy
This video is a complete and detailed explanation of Combined Translational and Rotational Motion, specially designed for JEE Physics, IIT JEE aspirants, and Class 11 & Class 12 students.
If you are searching for rotational motion class 11, rotational motion class 12, or jee rotational motion physics, this lecture will help you build strong conceptual clarity.

In this lecture, we deeply discuss combined translational rotational motion, where a body like a wheel or disc undergoes linear motion as well as angular motion simultaneously. This topic is extremely important for JEE Main, JEE Advanced, NEET, and other competitive exams.
🔹 What You Will Learn in This Video
✔ Concept of pure rolling motion physics
✔ Difference between forward rolling and backward rolling
✔ Velocity in rolling motion at different points of a wheel
✔ Acceleration in rolling motion, including
– Linear acceleration
– Tangential acceleration
– Centripetal acceleration
✔ Angular acceleration rolling motion explained with diagrams
✔ Pure rolling condition using velocity and acceleration
✔ Kinetic energy rolling motion (translation + rotation)
✔ Use of the radius of gyration in physics
✔ Important JEE-level numericals from rolling motion physics
This lecture is perfect for students preparing for physics rolling motion numerical and those who find jee physics rotational concepts confusing.
🔹 Velocity in Rolling Motion (Very Important for JEE)
In rolling motion physics jee, velocity is one of the most asked concepts.
In this video, we explain how velocity in rolling motion changes from point to point:
• Velocity at bottom point (pure rolling condition)
• Velocity at centrefor of mass
• Velocity at topmost point (2V condition – very important for JEE)
Many IIT JEE physics rotation questions are directly based on these velocity concepts.
🔹 Acceleration in Rolling Motion Explained Clearly
Most students struggle with acceleration in rolling motion, so this lecture explains it step by step.
We cover:
• Linear acceleration of the center of mass
• Tangential acceleration due to angular acceleration
• Centripetal acceleration due to angular velocity

The concept of pure rolling motion physics is again discussed using acceleration, which is crucial for neet jee rotational motion questions.
🔹 Kinetic Energy in Rolling Motion
This video also includes a full derivation and explanation of kinetic energy rolling motion.
Total kinetic energy in combined motion is:
• Translational kinetic energy
• Rotational kinetic energy
Using radius of gyration physics, we derive:
• Ring / hollow cylinder
• Disc / solid cylinder
• Solid sphere
• Hollow sphere
These formulas are extremely useful for jee rotational motion physics problems.
