Answer / Explanation:
acceleration is essentially increasing in velocity. [acceleration is literally velocity over time]
So, we can see acceleration on this velocity/time graph (the y-axis is representative of velocity).
Meaning that...
When we increase in velocity, that is acceleration. [A]
When we stay at the same velocity, that is zero acceleration. [B]
<em>> (we are not increasing {acceleration} or decreasing {deceleration} in velocity/ acceleration over time)</em>
When we decrease in velocity, that is deceleration. [C]
When we have <em>no</em> velocity (velocity = 0), that is zero velocity. [D]
So, this curve is already in order of A-B-C-D.
(origin/0 to A = acceleration)
(A to B = zero acceleration)
(B to C = deceleration)
(C to S = zero velocity)
hope this helps!!
Answer:
20 m/s
Explanation:
The acceleration of an object determines the increase in velocity per second.
In this case the acceleration is 20m/s^2.
That is, the increase is 20m/s each second.
I hope this is useful for you

Answer:
A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.
Answer:
it depends on the density.
an object can be small but way more.
