4. State in words how acceleration is calculated. __

## Step 1<br />Acceleration is a measure of how quickly an object's velocity is changing. It is a vector quantity, meaning it has both magnitude and direction.<br /><br />## Step 2<br />The formula for acceleration is given by:<br />### \(a = \frac{\Delta v}{\Delta t}\)<br />where \(a\) is acceleration, \(\Delta v\) is the change in velocity, and \(\Delta t\) is the change in time.<br /><br />## Step 3<br />In this formula, \(\Delta v\) represents the difference between the final and initial velocities of the object, and \(\Delta t\) represents the time over which this change occurs.<br /><br />## Step 4<br />By dividing the change in velocity by the change in time, we get the acceleration. This formula essentially tells us how much the velocity of an object is changing per unit of time.
