Rest And Motion

• Motion: An object is said to be in motion when its position changes with time.

• Rest: An object is said to be at rest when its position does not change with respect to a reference point with time.

• A specific point with respect to which we describe the location of an object is called a reference point.

• The terms Rest and Motion are relative.
