Difference Between Inertial & Non-Inertial Frames | Practice Numericals

Click For Summary
Inertial frames of reference are those that move at a constant velocity or remain stationary, while non-inertial frames are accelerating or rotating. The discussion highlights the need for clarity on these definitions, particularly in the context of rotational motion. Participants seek resources for practicing numerical problems related to angular momentum, moment of inertia, and torque. Understanding these concepts is crucial for mastering physics topics involving rotational dynamics. The conversation emphasizes the importance of distinguishing between these two types of frames for effective problem-solving in physics.

i came over the terms 'inertial' and 'non-inertial' frames during the study of rotational motion...pls clarify the difference...! plus can anyone give me a link from where i can practice numericals of angular momentum, moment of inertia, torque..

A non inertial frame of reference is a frame of reference where the frame is accelerating or rotating. An inertial frame moves at a constant velocity or is stationary.
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
