Acceleration is change of velocity per time unit; the SI unit is meters per second per second, usually abbreviated as "meters per square second".
Define these Levels of Measurement.NominalOrdinalInterval/Ratio
Measurement is the measure of something or someone.
The noun form of "define" is "definition." It refers to a statement of the exact meaning of a word or phrase, typically found in a dictionary or other reference source.
It actually means this. Increase in the rate or speed
Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.
its so hard to define....
That means that the acceleration of an object is caused by the force of gravity acting on the object.
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
European measurement system
the linear measurement in T.D. is a measurement which uses lines to figure letters and numbers by its sizes.
Is 'eadies' the right spelling?
Yes, it just depends on how you define which way is "positive". If you define the "backwards" direction to be the positive direction, acceleration will be positive when going "backwards". Note that if we define the axes like this, going "forwards" will give the car a negative acceleration.
