Duration
Speed (ex: meters/second, miles/hour)
A change in velocity is acceleration, so a accelerometer
A vector quantity measures both speed and direction at the same time. Velocity is an example of a vector quantity, as it includes both the magnitude (speed) and the direction of an object's motion.
The unit of frequency is reciprocal time ... "per second", or Hertz.
The average speed measures the speed during an entire trip. It is calculated by dividing the total distance traveled by the total time taken.
Time
Time
He measures times by events his experiences rather than by societal measures time.
The answer depends on what the "b" measures are and how they differ from the "a" measures and also "c" and other subsequent measures.
velocity
a barometer measures air pressure. an anemometer measures wind speed. a thermometer measures temperature.
A horologist measures time.
Describe a time when you anticipated potential problems and developed preventive measures?
Rain gauze measures precipitation at the given place and time.
A dogs toe.
speed
A rate is a ratio which measures a certain variable in an amount of time. The most common rate would be distance / time (which measures speed).
