Centripetal acceleration is ...

• Acceleration toward the center of a curved or circular path
• Acceleration toward the outside of a circle
• Vertical motion instead of horizontal motion

Centripetal force is...

• The net force exerted toward the center of a curved path
• The net force exerted to the outside of a circle
• The force going against gravity
