Question

Which statement best explains acceleration? It is the total distance covered over a period of time. It is a change in velocity over a period of time. It is a change in displacement over a period of time. It is a change in direction over a period of time.

Answer 1

Acceleration is the ratio of

a change in velocity
to
the time over which the change happened.

Answer 2

Answer: Option (c) is the correct answer.

Step-by-step explanation:

Acceleration is defined as the change in velocity over a period of time.

Mathematically,
`a = (dv)/(dt)`

where dv = change in velocity

dt = change in time

Thus, we can conclude that out of the given options, the statement acceleration is a change in displacement over a period of time best explains acceleration.
