Question

When divided by △t, (vf - vi) is used to determine which characteristic? A.Speed B.Direction C. Displacement D.Acceleration

Answer 1

Answer:

D.Acceleration

Explanation:

The acceleration of an object is defined as:

$a=\frac{v_f -v_i}{\Delta t}$

where

vf is the final velocity of the object

vi is the initial velocity of the object

$\Delta t$ is the time taken for the change in velocity to occur

Therefore, from the formula, we see that if we divide (vf - vi)  by △t, we get the acceleration.
