GENERAL KNOWLEDGE

Detailed explanation-1: -A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that we call stationary-such as a tree, a sign, or a building-make good reference points.

Detailed explanation-2: -Stationary reference points are important to use because if your reference point is in motion, you will not be able to tell if you or your reference point is in motion, or you will think you are moving faster or slower than you really are. Movement in relation to a frame of reference.

Detailed explanation-3: -Objects that are fixed relative to Earth – such as a building, a tree, or a sign-make good reference points.

Detailed explanation-4: -You don’t always need to see something move to know that motion has taken place. A reference point is needed to determine the position of an object. Motion occurs when an object changes its position relative to a reference point. The motion of an object depends on the reference point that is chosen.

Detailed explanation-5: -In either situation motion is when an object changes position compared to a reference point. Not all reference points have to be standing still. An example of a reference point that is moving is when you look out the window of a car and notice that you are moving faster than the car next to you.
