Detailed explanation-1: -An object is said to be in motion, if its position changes with respect to its surroundings and time.
Detailed explanation-2: -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 are fixed relative to Earth – such as a building, a tree, or a sign-make good reference points.
Detailed explanation-3: -Something is in motion if it is changing position. It could be a fast-moving airplane, a leaf swirling in the wind, or water trickling from a hose. Even your school, attached to Earth, is moving through space. When an object moves from one location to another, it is changing posi-tion.
Detailed explanation-4: -Answer: An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object’s distance from another object [reference point] is changing.
Detailed explanation-5: -If an object moves relative to a reference frame-for example, if a professor moves to the right relative to a whiteboard, or a passenger moves toward the rear of an airplane-then the object’s position changes. This change in position is known as displacement.
