Coriolis- and Centrifugal Force in a Rotating Frame of Reference

Hey Coriolis and centrifugal force in a rotating frame of reference as 1 can see with these clouds error

does not move straight into a zone of low pressure but on a spiral the rotation of a low pressure storm on the northern hemisphere is opposite to

1 on the southern hemisphere to study the phenomenon in a rotating frame of reference

we examine the movement of a ball from 2 or different frames of reference the a disk with a radius of 23 . 5 centimeters rotates around its centre 1 camera is connected to the table and shows the inertial frame of reference the other rotates with the disk and thus shows a rotating frame of reference here the schematic setup of the

experiment the ball it accelerated by a gravitational force in a guide rail and keeps moving practically force-free with constant speed after leaving it in the

picture of the camera in the inertial frame of reference on the top left the table in the background appears to be fixed In the rotating frame of reference on the top right the background seems to rotate why the disk is fixed 1 has to remember that both cameras show the same experiment recorded at the same time the angular speed is 1 hertz but

to examine the trajectories we register the position of the ball with the red dot the because of the limited frame rate of the camera the position of the ball is unclear on some pictures the inaccuracy of the measured position of the ball is approximately 1 centimeter radially and 1 degree tangentially the time measurement starts when the ball is in the center of the disk check for a quantitative analysis we use polar coordinates with 0 degrees in the direction the ball moves when heating the guide rail here 1 sees the complete

diagram in polar coordinates the

the same movement is now examined in the rotating frame of reference using the

same method check the position of the ball is again

shown in polar coordinates

In the inertial frame of reference the ball

moves nearly on a straight line it moves along a curve in the rotating frame of reference although it is the same experiment examined in both cases the measured values

location and velocity and acceleration are denoted ah V and 80 in the inertial frame of reference the In the rotating frame of reference and apostrophes analyzing the results 1 sees while the ball in the inertial frame of reference moves nearly force-free and thus without acceleration this is not true for the rotating frame of reference they're the acceleration is unequal to 0 the this means that 1 has to implement inertial forces because of the relative acceleration of the systems With this inertial force the movement of the ball can be explained in both systems using Newton's 2nd Law the thus the rotating frame of reference is a non-inertial frame of reference the transformation of location velocity and acceleration between both frames requires e questions of transformation the additional force in the rotating frame of reference is composed of Coriolis force and centrifugal force the the Coriolis force takes effect perpendicular to the velocity of the examined element the centrifugal force is always directed outwards
