Question

How do you determine the acceleration of an object?

Answer 1

Are you familiar with any basic calculus? If so, we can just look at this derivative and see what's happening with our units here..

$a = \frac{dv}{dt}$

Here it shows that acceleration is the derivative of velocity with respect to time. In other words, we can say that:

$a=\frac{\Delta v}{\Delta t}$

We can read that equation as: "acceleration is the change of velocity divided by the change in time (aka the time interval)."

If you're not familiar with calculus, we can use a simple equation of motion:

$v_f = v_i+at$

where:

vf = final velocity

vi = initial velocity

a = acceleration

t = observed time interval

We can rearrange this equation to find:

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

This is the same exact thing we wrote before!

Answer 2

Answer:the correct option is A

Explanation:

To determine the acceleration of an object, you divide the change in velocity by the time interval
