Circular Motion

The velocity is always _____ to the line of a circle. 

• outwards
• towards the center
• tangent
• faster

As the car goes around the curve, the centripetal force is directed--

• toward the center of the circular curve

• away from the center of the circular curve

• tangent to the curve in the direction of motion

• tangent to the curve opposite the direction of motion

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
