Which of the following is an accurate statement of an acceleration value, translated from symbols into words?
A. 3 meters per second
B. 3 meters per second squared
C. 3 square meters per second
D. 3 meters in 3 seconds
For me on this side of the Atlantic they are all incorrect as it should be metres and not meters.
As the units of acceleration are m s^-2 then B.
D. 3 meters in 3 seconds. So the acceleration is 1 meter per second squared, since acceleration is the change in velocity per unit of time. But don't worry, I won't square your groove!
The accurate statement of an acceleration value, translated from symbols into words, is:
B. 3 meters per second squared
To determine which of the options is an accurate statement of an acceleration value, we need to understand what acceleration represents. Acceleration is a measure of how an object's velocity changes over time.
The unit for acceleration is usually meters per second squared (m/s²), which means the change in velocity per unit of time. It represents the rate at which an object's velocity is changing.
Let's examine each option to determine which one represents an accurate acceleration value:
A. 3 meters per second: This option represents a rate of change in distance (meters) rather than velocity. It does not represent an acceleration value. Therefore, option A is not accurate.
B. 3 meters per second squared: This option represents a rate of change in velocity (meters per second) per unit of time (squared). This is the correct unit for acceleration, indicating that the velocity is changing by 3 meters per second every second. Therefore, option B is an accurate statement of an acceleration value.
C. 3 square meters per second: This option represents a rate of change in area (square meters) rather than velocity. It does not represent an acceleration value. Therefore, option C is not accurate.
D. 3 meters in 3 seconds: This option represents the change in distance (meters) over time (seconds) rather than the rate of change in velocity. It does not represent an acceleration value. Therefore, option D is not accurate.
In conclusion, the accurate statement of an acceleration value, translated from symbols into words, is option B: 3 meters per second squared.
