Final answer:
The sensation of knowing a car is moving with your eyes closed is due to the movement of tiny hair cells in the semicircular canals of the inner ear.
Step-by-step explanation:
The sensation of knowing a car is moving with your eyes closed is due to the movement of tiny hair cells in the semicircular canals of the inner ear. The semicircular canals are fluid-filled loops that detect angular acceleration and deceleration from rotation. When the head turns, the fluid in the canals shifts, bending the hair cells and sending signals to the brain. This allows us to perceive the sensation of movement even without visual input.
