### rate:

Velocity
* Velocities are apparent velocities, computed along a straight array
  - heliocentric
  - relative to the Pacific plate
  - very similar in saturated, unconsolidated sediments
  - can vary laterally along a given layer, and layers can pinch out
  - increase with average crustal age along ray paths
* affects the amount of economic activity generated by a given money supply.
* also increases with increasing salinity and temperature.
* combination of energy and drive, combining the physical and the mental.
* depends on compressibility, shear strength and density of material
  - primarily on temperature, less on pressure, and very little on salinity
* describes both the speed and direction of an object.
* differs from speed in that it has both a magnitude and a direction.
* equals mass times acceleration.
* exists only in computers and in the mind of mankind.
* gives distance, time, and the direction of travel.
* has the dimensions of length divided by time
  - same magnitude as speed, but is associated with a direction
* includes speed and direction of motion.
* increases with an increase in porosity.
* indicates the speed of an object in a direction of motion.
* is actually a vector with both direction and magnitude
  - speed with direction
* is also a part of momentum
  - vector quantity
  - dependent on the electrical conductivity and dielectric constant
  - displacement over time, where displacement is interchageable with distance
  - distance divided with time
  - equal to the distance travelled divided by the time take to travel it
  - expressed as horizontal and vertical elements
  - how fast something is moving in a given direction
  - in speed per unit
  - known as a vector quantity because it has both speed and direction
  - linear because it is increasing at the same amount each time interval, acceleration
* is measured by geophones generating the error signals that control the activators
  - using a current meter
  - with measuring sticks and stop-watches
  - motion, divided by the number of ticks on a clock that it takes for the motion to occur
  - similar to speed but it has direction
  - sort of the slope of the rotated coordinates
* is speed in a certain direction
  - specific direction
  - with a direction and is important in understanding bumper car collisions
  - such a quantity as is acceleration and force
  - the antiderivative of acceleration, which calculus determination
* is the change in distance divided by the change in time
  - position
  - of distance over change in time
  - direction and rate of change in position
* is the distance an object travels divided by time
  - objecttravels divided by time
  - first derivative of position
* is the measurement of the rate and direction of change in the position of an object
  - speed of the ground motion
  - primary factor affecting the ability of a stream to erode
  - rate at which the position changes
* is the rate of change of displacement of an object, with respect to time
  - location
  - position, and acceleration is the rate of change of velocity
  - motion in a specific direction
  - ratio of distance traveled to time
  - recessional velocity of a particular galaxy away from the observer
  - slope of a position-time graph
* is the speed of an object in a certain direction
  - in one direction
  - time it takes a floating object to travel a given distance
  - time-derivative of displacement
  - therefore also a vector quantity
  - to acceleration as appetite is to hunger
* measure of distance per unit time
  - the rate of change of position of an object
* measurement including both the speed of and the change in direction of an object
  - of speed using distance and time as the variables
* quantity that designates how fast and in what direction a point is moving.
* regulates the distance between each drip.
* specifies a direction to go along with that magnitude.
* speed with an associated direction.
* varies with location and time in a river.
* vector and is distinguished from speed in that it has a direction associated with it
  - measurement because it has an amount and a direction
* vector quantity and has both magnitude and direction
  - that indicates distance per time and direction
  - quantity, which consists of both a direction and a magnitude
  - which tells the system how fast and in what direction the particle is moving
* vector, because it speed in a certain direction
  - which means it has both a magnitude and direction
