Which of the following is NOTan example of centripetal force? driving in a straight line twirling a can tied to a string gravity washing machine basket in Spin cycle

## Step 1<br />Centripetal force is a force that makes a body follow a curved path. It is always directed towards the center of the path. <br /><br />## Step 2<br />In the given options, "twirling a can tied to a string", "gravity", and "washing machine basket in Spin cycle" are all examples of situations where an object is moving in a curved path. Therefore, they involve centripetal force.<br /><br />## Step 3<br />However, "driving in a straight line" does not involve a curved path. Therefore, it does not involve centripetal force.
