Detailed Solution

Movement of dust and leaves, flapping sound of windows due to breeze we cannot actually see a thing but can sense its motion.[96]
Rest and motion are two different states of an object or a person. An object or a person is said to be at rest when it doesn’t change its position with respect to a starting reference point, known as the origin. It is said to be in motion when it changes its position with respect to a starting reference point. Generally, we say a thing to be in motion when we can see it move, but there are instances when we cannot actually see a thing but can sense its movement. Some of the instances where we can sense the movement of the wind are the movement of leaves, the movement of windows due to the breeze, and the movement of dust particles when lighted. Stones at rest are not considered to be in motion.
