Unit 7 - Centripetal Force (Center Seeking Force)

Centripetal force is Latin for "center seeking" force

Centripetal force is not a type of force (ie friction, normal, gravitational, electric, tension)= It is a resultant vector pointing toward the center of rotation

Your body feels the opposite of a net force. When you accelerate upward on an elevator you feel as if you are being pushed downward and feel heavier. If the elevator accelerates downward you feel lighter, as if you are being pushed upward.

If you are driving your car and turn to the left, you feel as if you are being pushed to the right. It is actually your bodies inertia opposition that change in velocity. You are actually being pushed to the left by the friction between you and the seat.

I CAN STATEMENTS. I CAN

  • Create force diagrams that describe how things are pushed towards the center of a circle
  • Use kinematics to determine the speed of a moving object
  • Rank an objects centripetal force and centripetal acceleration in terms of the variables
  • Explain why things follow curved paths
  • Explain what "zero gravity" actually means.
