Comparing average acceleration and instantaneous acceleration,
A) average acceleration is not a vector quantity and therefore doesn't include direction.
B) both terms sometimes refer to the same quantity.
C) the two terms never refer to the same quantity.
D) none of the above apply.

Question

Quizplus · Accepted Answer

Average acceleration is calculated over a certain period of time and is therefore an average of the instantaneous accelerations during that time. Instantaneous acceleration, on the other hand, refers to the acceleration of an object at a specific moment in time. While the two terms may not always refer to exactly the same value, they are closely related and can overlap in certain situations. Additionally, both average and instantaneous acceleration are vector quantities that include both magnitude and direction.
