PHY102 Inertial frames ± There is a special class of frames of reference used in mechanics (PHY101) ² Inertial frames ± Move at constant velocity (special case v=0) ± Eg Otto viewed from Stolkin looks to be moving at constant velocity and also from the moving camera – an inertial frame. ± Such frames do not accelerate
