Unit 5 - Part 2 Centripetal acceleration Assessment What do you need to know about an object to calculate its centripetal force? acceleration and velocity distance and mass acceleration and mass mass and speed

## Step 1<br />The problem is asking us to identify the two quantities we need to know about an object to calculate its centripetal force. <br /><br />## Step 2<br />Centripetal force is the force that keeps an object moving in a circular path. It is always directed towards the center of the circle. <br /><br />## Step 3<br />The formula for centripetal force is given by:<br />### \( F = \frac{mv^2}{r} \)<br />where \( F \) is the centripetal force, \( m \) is the mass of the object, \( v \) is the speed of the object, and \( r \) is the radius of the circular path.<br /><br />## Step 4<br />From the formula, we can see that we need the mass of the object and its speed to calculate the centripetal force.
