Until It is important to know the exact Arabic words, for the discussion that follows.
However, this is a rough labelling: These results also can be obtained directly by two time differentiations of rB t. Agreement of the two approaches demonstrates that one could start from the general expression for fictitious acceleration above and derive the trajectories shown here.
However, working from the acceleration to the trajectory is more complicated than the reverse procedure used here, which is made possible in this example by knowing the answer in advance.
As a result of this analysis an important point Tornadoes vs hurricanes essay In particular, besides the Coriolis acceleration, the centrifugal force plays an essential role. It is easy to get the impression from verbal discussions of the cannonball problem, which focus on displaying the Coriolis effect particularly, that the Coriolis force is the only factor that must be considered,  but that is not so.
A somewhat more complex situation is the idealized example of flight routes over long distances, where the centrifugal force of the path and aeronautical lift are countered by gravitational attraction. While it travels, the thrower circles in a counter-clockwise direction.
The ball's motion as seen by the thrower, who now remains at The figure illustrates a ball tossed from On the left, the ball is seen by a stationary observer above the carousel, and the ball travels in a straight Tornadoes vs hurricanes essay to the center, while the ball-thrower rotates counter-clockwise with the carousel.
On the right the ball is seen by an observer rotating with the carousel, so the ball-thrower appears to stay at The figure shows how the trajectory of the ball as seen by the rotating observer can be constructed. On the left, two arrows locate the ball relative to the ball-thrower.
One of these arrows is from the thrower to the center of the carousel providing the ball-thrower's line of sightand the other points from the center of the carousel to the ball.
This arrow gets shorter as the ball approaches the center. A shifted version of the two arrows is shown dotted. On the right is shown this same dotted pair of arrows, but now the pair are rigidly rotated so the arrow corresponding to the line of sight of the ball-thrower toward the center of the carousel is aligned with The other arrow of the pair locates the ball relative to the center of the carousel, providing the position of the ball as seen by the rotating observer.
By following this procedure for several positions, the trajectory in the rotating frame of reference is established as shown by the curved path in the right-hand panel. The ball travels in the air, and there is no net force upon it.
To the stationary observer the ball follows a straight-line path, so there is no problem squaring this trajectory with zero net force. However, the rotating observer sees a curved path. Kinematics insists that a force pushing to the right of the instantaneous direction of travel for a counter-clockwise rotation must be present to cause this curvature, so the rotating observer is forced to invoke a combination of centrifugal and Coriolis forces to provide the net force required to cause the curved trajectory.
Bounced ball[ edit ] Bird's-eye view of carousel. The carousel rotates clockwise. Two viewpoints are illustrated: Both observers agree at any given time just how far the ball is from the center of the carousel, but not on its orientation.
The figure describes a more complex situation where the tossed ball on a turntable bounces off the edge of the carousel and then returns to the tosser, who catches the ball.
The effect of Coriolis force on its trajectory is shown again as seen by two observers: The figure shows a bird's-eye view based upon the same ball speed on forward and return paths. Within each circle, plotted dots show the same time points.
In the left panel, from the camera's viewpoint at the center of rotation, the tosser smiley face and the rail both are at fixed locations, and the ball makes a very considerable arc on its travel toward the rail, and takes a more direct route on the way back.
From the ball tosser's viewpoint, the ball seems to return more quickly than it went because the tosser is rotating toward the ball on the return flight. On the carousel, instead of tossing the ball straight at a rail to bounce back, the tosser must throw the ball toward the right of the target and the ball then seems to the camera to bear continuously to the left of its direction of travel to hit the rail left because the carousel is turning clockwise.
The ball appears to bear to the left from direction of travel on both inward and return trajectories.
The curved path demands this observer to recognize a leftward net force on the ball. This force is "fictitious" because it disappears for a stationary observer, as is discussed shortly.
For some angles of launch, a path has portions where the trajectory is approximately radial, and Coriolis force is primarily responsible for the apparent deflection of the ball centrifugal force is radial from the center of rotation, and causes little deflection on these segments.
When a path curves away from radial, however, centrifugal force contributes significantly to deflection. The ball's path through the air is straight when viewed by observers standing on the ground right panel.
In the right panel stationary observerthe ball tosser smiley face is at 12 o'clock and the rail the ball bounces from is at position one 1. From the inertial viewer's standpoint, positions one 1two 2three 3 are occupied in sequence.Hurricanes and tornadoes are both stormy atmospheric systems that have the potential to cause destruction.
They are caused by instability in atmospheric conditions. According to the region and severity of stormy conditions, hurricanes may also be referred to as typhoons or tropical cyclones. Hurricanes and tornadoes are some of the most violent natural occurring disasters known to mankind.
Some on the gulf coast see hurricane opal as a distance memory, but most are reminded of her every time they drive on highway 98 and see the sand dunes building back from nothing to . Hurricane r-bridal.como Essay Hurricanes and tornados are both devastating forces of nature.
Both weather phenomenon cause great amounts of damage and destruction. One of the most common misconceptions is that both hurricanes and tornados are simply different names for the same thing.
However, that is not true. “IRAN HAS NO NUCLEAR WEAPONS,” Prime Minister Vladimir Putin told his fellow Russians during his annual Question-and-Answer session on December 3, Only a few days before Putin’s nationwide address, Iranian President Mahmoud Ahmadinejad, with threats from Israel on Iran’s nuclear sites.
