Is Earth an inertial frame?

we approxiamte earth to be an inertial frame .....yes newtons law can be applied from space

i wud say dat since we r on the earth n we do experiments on the earth so wid respect to us earth is an interial frame bt if we see the same experiment from other planet then it wud becum an non-interial frame coz of centipetal acc.wat do u think??

First of all let me make it clear that the earth is indeed a non-inertial frame of reference. We consider it as inertial because under experimental conditions the variations are so small that they can be neglected. From space these effects are nullified. So Newton's laws are applicable.

i think tht ........as the acceleration of earth is very small .....abt 0.27m/s² .........we neglet it nd consider it as inertial framee...........................
