> [!summary] Frames are reference are a statement where you choose an object to be at rest. >[!info]+ Read Time **⏱ 1 min** # Definition Frames of reference in an idea where you choose an object to be "stationary" and determine how other objects react relative to that "stationary" object. Inertial frames of reference are when you choose an object to be stationary, and objects relative to that object are moving at constant [[Velocity|velocity]]. Here, [[Newton Laws|Newton's laws]] hold. Non-inertial frames of reference occur when you choose an object to be stationary, and objects relative to that object seem to [[Acceleration|accelerate]] without a force. In this frame of reference, pseudo forces have to be introduced to hold [[Newton Laws|Newton's Laws]] # Resources <iframe width="560" height="315" src="https://www.youtube.com/embed/wD7C4V9smG4?si=EwAVNDg9ztvGMPbK" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
