Tidal force

The tidal force or tide-generating force is a gravitational effect that stretches a body along the line towards and away from the center of mass of another body due to spatial variations in strength in gravitational field from the other body. Weightlessness and tidal force are gravity.

Vertigo

Vertigo is a condition in which a person has the sensation that they are moving, or that objects around them are moving, when they are not.

Vestibular system

The vestibular system, in vertebrates, is a sensory system that creates the sense of balance and spatial orientation for the purpose of coordinating movement with balance.

Virulence

Virulence is a pathogen's or microorganism's ability to cause damage to a host.

X-ray crystallography

X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions.
