The meaning of the V sign is partially dependent on the manner in which the hand is positioned. Where the palm of the hand is facing inward toward the signer (i.e. the back of the hand faces the observer), this is seen as insulting gesture in Australia, Ireland, New Zealand, South Africa, and the United Kingdom.
"current": AC (for "alternating current"); less commonly, DC (for "direct current"); or even I (the symbol used in physics and electronics) Roman numerals: for example the word "six" in the clue might be used to indicate the letters VI; The name of a chemical element may be used to signify its symbol; e.g., W for tungsten
The volt (symbol: V) is the derived unit for electric potential, voltage, and electromotive force. [ 22 ] [ 23 ] The volt is named in honour of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile , possibly the first chemical battery .
Symbol Name Meaning SI unit of measure alpha: alpha particle: angular acceleration: radian per second squared (rad/s 2) fine-structure constant: unitless beta: velocity in terms of the speed of light c: unitless beta particle: gamma: Lorentz factor: unitless photon: gamma ray: shear strain: radian
t. e. Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
Velocity is a physical vector quantity: both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s −1). For example, "5 metres per second" is a scalar, whereas "5 ...
Unit of. electric potential, electromotive force. Symbol. V. Named after. Alessandro Volta. SI base units. kg ⋅ m 2 ⋅ s −3 ⋅ A −1. The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI).
v. t. e. Kinematics is a subfield of physics and mathematics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move. [1][2][3] Kinematics, as a field of study, is often referred to as the "geometry of motion" and ...
