Detailed explanation-1: -The Earth is the most common frame of reference. Whenever the frame of reference is not listed, assume that the motion is related to earth.
Detailed explanation-2: -Answer and Explanation: The sun is an inertial frame of reference for the earth as with respect to the earth; the sun is not accelerating. All those frames which are not accelerating are called inertial frames of reference.
Detailed explanation-3: -Because (almost) everyone is on Earth, we are essentially all in the same frame of reference. Nobody is wondering how fast they are going due to Earth’s spin compared to another. If you were to drive a car parallel to the train, the car and the train would be different frames of reference.
Detailed explanation-4: -A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another.
