GENERAL KNOWLEDGE

Detailed explanation-1: -Relative motion is movement in relation to a frame of reference. For example, as the train moves past a platform, people standing on the platform will see those on the train speeding by. But when the people on the train look at one another, they don’t seem to be moving at all.

Detailed explanation-2: -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.

Detailed explanation-3: -In physics, a frame of reference, or reference frame, is a perspective that one uses to determine if an object is moving. A frame of reference consists of an object or environment that is considered to be stationary.

Detailed explanation-4: -Frame of reference: When you are standing on the ground, that is your frame of reference. Anything that you see, watch, or measure will be compared to the reference point of the ground. If I am standing in the back of a moving truck, the truck is now my frame of reference and everything will be measured compared to it.
