Define motion and provide two examples of objects in motion and two examples of objects at rest.

A.VERIFIED ANSWERfact-checked by tutors

Motion is defined as the change in position of an object with respect to its surroundings in a given interval of time. Examples of objects in motion include a moving car, a flying bird, a rolling ball, or a person walking. Examples of objects at rest include a book lying on a table, a parked car, a house, or a tree.
