Question

12 multiple choice 1 point what is acceleration?
how fast velocity changes
total distance divided by total time
the speed at any moment or instant in time
all of the above
none of the above

Explanation:

• Recall the definition of acceleration: Acceleration is the rate of change of velocity, i.e., how fast velocity changes (in terms of magnitude or direction or both).
• "Total distance divided by total time" is the definition of average speed, not acceleration.
• "The speed at any moment or instant in time" is the definition of instantaneous speed, not acceleration.
• Since only the first option correctly defines acceleration, we can determine the answer.

Answer:

A. how fast velocity changes
