Question

Which part of the curve shows:

Answer 1

Answer:

O - A : acceleration

A - B : zero acceleration

B - C : deceleration

C - S : zero velocity

Explanation:

acceleration is velocity over time, meaning that the slope of the graph is showing acceleration

Answer 2

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]

> (we are not increasing {acceleration} or decreasing {deceleration} in velocity/ acceleration over time)

When we decrease in velocity, that is deceleration. [C]

When we have no 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!!
