Question

which formula helps us calculate change in velocity? *

change in velocity = (acceleration) / time

change in velocity = (acceleration) * time

change in velocity = (acceleration) - time

change in velocity = (acceleration) + time

Explanation:

Step1: Recall the formula for acceleration

Acceleration \(a=\frac{\Delta v}{t}\), where \(\Delta v\) is the change in velocity and \(t\) is the time.

Step2: Rearrange the formula for \(\Delta v\)

Multiply both sides of the equation \(a = \frac{\Delta v}{t}\) by \(t\). We get \(\Delta v=a\times t\).

Answer:

change in velocity = (acceleration) * time
