  • @lEtudel This is difficult to explain w/o visual aids, but I'll try anyway. In a low pressure system, air is coming in from everywhere around the system. On a sheet of paper, draw a circle with an L in the center to represent the storm. Now, draw arrows all around the circle pointing to the L. For the NH, the CF is to the right, so on the arrows you just drew, draw more arrows pointing to the right of the direction each original arrow is traveling. You'll notice this causes a CCW spin.

  • if the CF causes objects to deflect to the 'RIGHT' of their intended path in the NH, should hurricane and cyclones circulate 'CW' in the NH? why they circulate 'CCW' in the NH? i'm confused :(

  • If we are moving 1000+mph east, why is the speed of sound the same in both directions and there no apparent doppler effect while standing still on earth and yelling in one direction opposed to another. Because the the air is also moving around 1000+mph east and that is the medium in which sound travels? What about light. Is light moving faster away from us if we shoot a laser to west than if we shoot it to the east???

  • @MetalicStevie Well what's preserved is the velocity of the merry-go-round at the time the ball is thrown. Since to an observer above the merry-go-round there is no force other than gravity (and air resistance) acting on the ball, the horizontal trajectory of the ball is still straight -- except it forms an angle relative to the intended path (it misses the target).

  • some great inforamtion here thanks

  • At 1:54 the narrator announces that an observe sees the ball as traveling straight. This is false. The motion of the rotation of the marry-go-round is perserved even after the ball has been thrown. The ball would still veer of course and thus the path of the ball would curve.

  • some sweet info here

  • this was a very helpful video to help me understand my homework better. Thanks.

  • @geobiochem 1km = 0.62 miles

  • Aaah I can't understand these measurements!?! Can someone please explain how many kilometres a "mile" is?
