Which formula is used to find an object’s acceleration?

There are different formulas that can be used to find acceleration, depending on which quantities we know in the problem. For example:

1) If we know the mass of an object (m) and the force applied to it (F), we can find acceleration by using Newton's second law

2) If we know the initial velocity (vi), the final velocity (vf) of an object and the time taken (t) for this change in velocity to happen, we can find acceleration with the formula

since acceleration is defined as the rate of change of velocity per unit time.

the answer is 100. i just did this lesson and got a 100% on it. : )
