hey friend , This is one of the fundamental laws of physics, which states that a body will resist any change to its state of motion. It will remain at rest unless an external force is applied to it, and will remain in motion unless it is forced to halt. This, along with a complex system in our inner ear, is the reason for dizziness.
The vestibular system with the three canals.
This system in the inner ear is known as the vestibular system, and is responsible for maintaining the balance of our bodies. Through this system, our body senses whether it is upright or lying down, or whether it is in motion or standing still.
In the labyrinthian structure of the inner ear, there are three semicircular canals arranged at right angles to one another, such that each of the canals individually senses movement along the 3 axes. These canals are filled with a fluid called endolymph, which sloshes around as our bodies move. This endolymph resists changes in motion, and due to the inertia of rest, lags behind, which stimulates the nerve cells. These nerve cells come in the form of small hairs , which transmit the messages to the brain.
Now, when a spinning motion is initiated, the endolymph lags behind at first, and then continues to move at the same rate of motion. As soon as you stop, however, due to inertia, the fluid keeps on moving for a while. For that period of time, the nerve cells send messages to the brain that the brain is still spinning, which makes you dizzy. Eventually, this endolymph slows down and we return to normal.
