Non-Inertial Frames & Rotating Systems
The chapter discusses non-inertial frames of reference and introduces concepts such as pseudo-forces, rotating coordinate systems, and various accelerations related to rotating frames. It also covers practical applications, including natural phenomena influenced by the Coriolis effect and the Foucault pendulum, which demonstrates Earth's rotation. Finally, it encapsulates these ideas with useful formulas relevant to understanding motion in non-inertial frames.

What we have learnt
- An inertial frame of reference is one in which Newton's laws hold true without modifications.
- The five-term acceleration formula explains the relationship between various types of acceleration in rotating frames.
- Centripetal and Coriolis accelerations significantly affect moving objects in rotating systems.
Key Concepts
- -- Inertial Frame
- A frame of reference moving at constant velocity where Newton's laws are valid.
- -- NonInertial Frame
- An accelerated frame of reference where Newton's laws require pseudo-forces for their application.
- -- PseudoForce
- A fictitious force that acts opposite to the acceleration of a non-inertial frame.
- -- Centripetal Acceleration
- An acceleration directed towards the center of a circular path, essential to maintaining circular motion.
