Can be defined as how fast something moves
WebVelocity 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 (9m/s), then its velocity is 9 m/s to the east. The idea behind this is that speed doesn't tell us in which direction the object moves in a given frame of reference. WebAboutTranscript. Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the ...

Speed is how fast something moves. Velocity is speed with a direction. Saying Ariel the Dog runs at 9 km/h(kilometers per hour) is a speed. But saying he runs 9 km/h Westwardsis a velocity. Imagine something moving back and forth very fast: it has a high speed, but a low (or zero) velocity. See more Speed is measured as distance moved over time. Speed = Distance Time We can also use these symbols: Speed = Δs Δt Where Δ ("Delta") means "change in", and 1. smeans distance ("s" for "space") 2. tmeans time See more Speed is commonly measured in: 1. meters per second (m/s or m s-1), or 2. kilometers per hour (km/h or km h-1) A km is 1000 m, and there are 3600 seconds in an hour, so we can … See more When the speed does not change it is constant.
