Answer 1

Answer:changing velocity

Step-by-step explanation:

Answer 2

Answer: Changing velocity

Step-by-step explanation:

By definition acceleration is the variation of velocity
`V`in time. If we do an inverse operation, we will find velocity is the integral of acceleration
`a`:

`V= \int\limits^t_0 {a} \, dt` (1)

Solving and taking into account acceleration is constant:

`V= at + V_(o)` (2)

Being
`V_(o)` the initial velocity which was the resultant constant from the integration.

From (2) we can see the equation is similar to the equation of the line
`y=mx+b`, where
`a` in this case is the slope. This means there is a linear variation in velocity when acceleration is constant.
