Kinesiology 2241A/B Lecture Notes - Lecture 11: Centripetal Force
Document Summary
The force causing centripetal accelerations is called centripetal force (center seeking) As soon as you apply a force, you will see a force change in its net velocity (momentum equation) Accelerations, mass and therefore a force involved. As soon as you eliminate the force, it wants to follow newton"s law and follow a straight path. There always has to be an equal and opposite reaction force. Trying to break it away from the curved path and make it go in a straight direction. Has the same magnitude and dimensions but in opposite direction. Drag occurs because you are cutting through the air (medium), the air pressing up against the sleigh is slowing you down. Friction occurs because there is contact with the ice. Centrifugal force is trying to break the individuals on a turn. Centripetal force is trying to draw you into the center.
