Answer 1

Velocity changes in displacement divided by time. Acceleration is the change in velocity divided by time.

Answer: Option 2

Step-by-step explanation:

Acceleration is defined as the rate of velocity changes of an object in a given time period. This can express in the equation as follows,

`\bold{a = (v)/(t) m / s^(2)}`

There two types in it as linear and radial acceleration. When velocity changes in the opposite direction to an object then it is called deceleration. But these are the same as a change in velocity.

Answer 2

2. Change in velocity

Step-by-step explanation:

The units that acceleration use are distance/time^2
`(m/s^2)` (in metric units).

The acceleration is the change of velocity over time, so

`(dv)/(dt) =(dx)/(dt)*(1)/(dt)`

In another way, if the velocity is constant, the acceleration is zero, but if the velocity change over the time (as a car do when the red light change), the acceleration takes value!.
