3. Give two ways the unit for acceleration can be written. __

## Step 1<br />Acceleration is a measure of how quickly an object changes its velocity. It is a vector quantity, meaning it has both magnitude and direction. <br /><br />## Step 2<br />The standard unit for acceleration in the International System of Units (SI) is meters per second squared (m/s²). This unit is derived from the formula for acceleration, which is the change in velocity (in meters) divided by the change in time (in seconds).<br /><br />## Step 3<br />Another way to express acceleration is in terms of distance over time cubed (e.g., kilometers per hour cubed). This unit is less commonly used, but it can be useful in certain contexts, such as when discussing the acceleration of a vehicle over a long distance.
