Question
Newton postulated that inertial frames of reference do exist. This statement, coupled with the definiti considered a more proper way to state Newton's 1st law Only an experiment can establish whether a particular frame of reference is inertial (or, to be precise, needed). Let us go back to the car example. The frame of reference attached to the ground, we woule an object and make sure that all external forces acting on it add up to zero, we can then observe that velocity (or, possibly, remaining at rest). In most problems that we will be solving, the frame of referen inertial frame of reference. For all practical purposes, this means that Newton's 2nd law will work in it. ns of eptual y for However, it is instructive to understand that the earth provides a reference frame that is less than "perf for instance, would notice that the object in question does, in fact, have an acceleration: the centripeta motion of the earth around the sun! The best inertial frame of reference is the one assoicated with dist reference that is moving at a constant velocity relative to distant stars. The conceptual questons that follow should help you learn to apply Newton's 1st and 2nd laws proper we will assume that the frame of reference associafed with the earth is perfectly inertial. Part A Which object provides an inertial frame of reference? O O 0 O the tip of the moving second hand of a clock a rock thrown vertically upward a pendulum swinging with no air resistance a skydiver falling at terminal (constant) velocity Submit Request Answer Part B You are conducting an experiment inside an elevator that can move in a vertical shaft. A load is hung wExplanation / Answer
Inertial frame means frame of reference is at rest or it has net zero acceleration
Here in all case there is accelereted frame but in 4th option net acceleration is zero ( because mg = drag force hence net force acting on them is zero) therfore sky diver falling at terminal speed is a case of inertial frame of reference
