A change in velocity over a time interval is called an acceleration if the velocity is increasing, or a decelleration if the velocity is decreasing.

This is an object's change in motion per unit time in a specified direction?

The phrase "change in motion" is rather slippery.The size of the change in the object's position, per unit time, in a specifieddirection, is the component of its velocity in that direction.The size of the change in the object's velocity, per unit time, in a specifieddirection, is the component of its acceleration in that direction.


Why is acceleration a rate?

Acceleration means how fast velocity changes. "How fast" means change of velocity per time unit - and this is also called a "rate".Acceleration means how fast velocity changes.

Is velocity matter?

No, velocity is a mathematical concept (change in position per unit time).


Why can power and velocity each be considered rates?

Its to do with constant values, the rate of acceleration refers to a constant change of velocity over time, so an acceleration of 10 (m/s)/s is a constant increase of velocity per unit time ( increase of 10 metres per second, every second )Velocity is a constant increase in distance, per unit time (metres per second)


Why does the unit of time enter twice in the unit accereration?

It should be noted that an acceleration is not a velocity. Velocity is defined as distance per unit rate; thus, it has dimensions of length/time. Acceleration is defined as change of velocity per unit rate; thus, its dimensions are velocity / time, i.e., (length/time) / time.


What is to measure change in speed per time?

An accelerometer is an instrument to measure acceleration, which is the change in velocity per unit of time.
