Non inertial frames are frames that have either angular or linear (or both) accelerations that are not equal to zero. [[Newton%27s_Laws_of_Motion|Newton's laws of motion]] do not apply in these frames. Objects observed from within appear to violate [[Newton%27s_Laws_of_Motion|Newton's laws of motion]]. [[Fictitious forces]] such as the [[Coriolis effect]] and centripetal acceleration can be explained through the use of non inertial reference frames. Both are caused by the acceleration of the reference frame itself. | Non inertial frames are frames that have either angular or linear (or both) accelerations that are not equal to zero.
