The rate at which velocity is changing at a given instant is described by
-instantaneous acceleration
-average speed
-constant speed
-vector addition

Respuesta :

instantaneous acceleration

Answer:

-instantaneous acceleration

Explanation:

As we know that the acceleration is defined as the rate of change in velocity and it is given by the formula

[tex]a = \frac{\Delta v}{\Delta t}[/tex]

here we know that

[tex]\Delta v [/tex] = change in velocity

[tex]\Delta t [/tex] = time interval

now if the time interval is very small then this instantaneous change in velocity with respect to small interval of time is known as instantaneous acceleration.

[tex]a_{ins} = \frac{dv}{dt}[/tex]

so correct answer will be

-instantaneous acceleration
