The force that is necessary to keep the bucket swinging in a circle is called the:

• tangential velocity
• centrifugal force
• centripetal force
• the force of gravity

The time taken for one complete circuit is called the... 

• Period
• Frequency 
• Angular velocity

Which is true about net force keeping it in a circle and centripetal acceleration?

• The centripetal acceleration is always pointing toward the center of an orbit and the net force keeping it in a circle is always pointing outward

• The centripetal acceleration is always pointing outward from the center of an orbit and the net force keeping it in a circle is always pointing inward

• The centripetal acceleration is always pointing toward the center of an orbit and the net force keeping it in a circle also pointing toward the center but in a totally different location

• The centripetal acceleration is always pointing toward the center of an orbit and the net force keeping it in a circle also pointing toward the center and in the same exact location as the centripetal acceleration
