#### Storyboard Text

• Uniform circular motion is the motion of an object in a circle at a constant speed.
• Can you help me understand uniform circular motion?
• The acceleration vector points to the center of the circle. Since it seeks the center of the circle it is identified as the "centripetal acceleration.
• An example of uniform circular motion is a ferris wheel. The velocity vector of the ferris wheel is tangent to the circle (identified as the tangential velocity.)
• The centripetal force is the force that also points to the center of the ferris wheel.
• I understand now, this means to make the circular motion, there must be a net or unbalanced force towards the center of the circle in order to deviate the object from its tangential path. Lets go to the carnival. I'm tired of studying.
• I thought you were tired of studying?
• Let's find the circumference of the ferris wheel!
