Velocity - Wikipedia
WebVelocity is the speed in combination with the direction of motion of an object. Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity: both magnitude and direction are needed to define it.
Velocity - Simple English Wikipedia, the free encyclopedia
WebFrom Simple English Wikipedia, the free encyclopedia. Velocity is a measure of how fast something moves in a particular direction. To define it needs both magnitude and direction. If an object moves east at 9 metres per second (9 m/s), then its velocity is 9 m/s to the east.
What is velocity? (article) | Khan Academy
WebAverage velocity is defined to be the change in position divided by the time of travel. v a v g = Δ x Δ t = x f − x 0 t f − t 0. In this formula, v a v g is the average velocity; Δ x is the change in position, or displacement; and x f and x 0 are the final and beginning positions at times t f and t 0 , respectively.
Velocity | Speed, Acceleration, Motion | Britannica
WebApr 25, 2024 · velocity, quantity that designates how fast and in what direction a point is moving. A point always moves in a direction that is tangent to its path; for a circular path, for example, its direction at any instant is perpendicular to a line from the point to the centre of the circle (a radius).
Terminal velocity - Wikipedia
WebTerminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force ( F d ) and the buoyancy is equal to the downward force of gravity ( F G ) acting on the object.
Flow velocity - Wikipedia
WebFlow velocity. In continuum mechanics the flow velocity in fluid dynamics, also macroscopic velocity [1] [2] in statistical mechanics, or drift velocity in electromagnetism, is a vector field used to mathematically describe the motion of a continuum. The length of the flow velocity vector is scalar, the flow speed .
Radial velocity - Wikipedia
WebThe radial velocity or line-of-sight velocity of a target with respect to an observer is the rate of change of the vector displacement between the two points. It is formulated as the vector projection of the target-observer relative velocity onto the relative direction or line-of-sight (LOS) connecting the two points.
Speed - Simple English Wikipedia, the free encyclopedia
WebSpeed is a measure . It is velocity but without the direction. [1] [2] [3] [4] Finding speed. Speed is the distance an object moves in a given amount of time. [1] [2] [3] The distance is never negative. [5] . If a train takes 1 hour to travel 100 kilometers, it has a speed of 100 kilometers per hour (62 mph). In fact this is the average speed. [3]
4 Ways to Calculate Velocity - wikiHow
Web6 days ago · 1. Find average velocity when acceleration is constant. If an object is accelerating at a constant rate, the formula for average velocity is simple: [3] . In this equation is the initial velocity, and is the final velocity. Remember, you can only use this equation if there is no change in acceleration.
