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 1The problem is asking us to identify the two quantities we need to know about an object to calculate its centripetal force. ## Step 2Centripetal force is the force that keeps an object moving in a circular path. It is always directed towards the center of the circle. ## Step 3The formula for centripetal force is given by:### where is the centripetal force, is the mass of the object, is the speed of the object, and is the radius of the circular path.## Step 4From the formula, we can see that we need the mass of the object and its speed to calculate the centripetal force.
