There is no coriolis effect in ballistics! Unless of course you are shooting over the north or south pole. The earth is spinning over 1000 mph at the equator and the same reason helicopters cant fly 1000 mph just by lifting off applies to the bullet as well. Because the bullet was traveling at the same 1000mph as the ground and the atmosphere when it was fired it maintains its same inertial force, unrestricted. Any shooter adjusting for the rotation of the earth, only hits his target by pure luck and correction of miscalculation.

I'm not so sure. He keeps saying it's an optical illusion, and he's right, because the ball isn't actually deflecting, it's going in a straight line. The Coriolis Effect is supposed to be a real thing with actual deflection and actual effects, such as explaining the difference spin in weather patterns between the hemispheres (but not explain toilets lol, that's different). In this experiment, there's no spin, it's just an optical illusion like he says.

@@skipperry63 Yes it is. They see it as curving, but it's actually going in a straight line. Anyway, I went and looked it up from a few other sources to check, and the Coriolis Effect is described as the reason cyclones form clockwise or CCW depending on the hemisphere (seems like BS because toilets do the same without any "deflection"). The video here seems to be describing the Coriolis FORCE, which doesn't look so much like a force as a method to calculate moving reference frames using Newtonian physics or some such. Personally I think they misapply this in science, since the weather is controlled by the magnetic field of the Earth and its interaction with the Sun. The weather isn't dragged along; it's part of the planet and moves along with it in much the same way the arms of galaxies don't lag behind and wind up the whole galaxy into a ball or the component parts of an atom don't do the same. Anyway I digress. It's definitely an optical illusion. It looks like it's curving, but it isn't. The people are.

@@grawss It is not a real force, though. It is a fictitious force, because the observers on the carousel "invent" it to explain the curved trajectory that they observe. For a stationary observer not bound to the rotational reference frame, the ball continues its motion in a straight line. A shot from the narrator's angle would have made it clear. If there was a stationary camera outside the carousel right behind the girl when she threw it, we would have seen the ball travel in a straight line.

It's coriolis force/effect

What this video fails to explain is that the example of the coriolis effect it is showing only applies if the object passes over the center point of the spinning circle or the ball remains in the air long enough for its inertial force to carry it beyond the circle and/or the intended target to change its direction of travel . She could have thrown the ball to the persons next to her without the ball being affected. (Other than air resistance)

No, the path will appear curved in their frame of reference regardless of the direction it's launched in. If she threw it to her right, when she's gone half way around it will now be on her left and from her point of view it will have curved around behind her. If they are rotating anticlockwise, an object moving in a straight line will always appear to be curving clockwise, regardless of the direction. For the person opposite her to catch it, her best chance is to throw it towards the person on her left, because that's where the person opposite will be a moment later when the ball arrives there, depending on the speed of course.

The key point is that the trajectory of the ball APPEARS TO THE OBSERVER IN THE ROTATING FRAME to be curving. The rotating frame creates a fictitious acceleration that appears to throw the ball off from its straight line trajectory.

@@mohit4715 Incorrect. Her tangential velocity has nothing to do with the velocity of the ball. Let's say the merry-go-round has a radius of 1m, and she throws the ball at 1m/s. Thus it takes 2s for the ball to reach the other side, because the diameter is 2m. NOW, if the merry-go-round is spinning at .25 revolutions per second, then in those 2s it takes the ball to cross, the ring has rotated .5 revolutions or 180 degrees. Therefore the girl rotates to the opposite side of the disk, catching the ball that she herself threw from the other side.

I believe this is a little misleading, or at least incomplete. Coriolis effect implies an inertial force, thus acceleration, in the non-intertial frame of reference (i.e. the merry-go-round). This force is not just an optical illusion, but rather a cinematic effect due to the velocity of the ball in a rotating frame of reference. When the ball is thrown it has a tangential velocity that is directly proportional to the radius (i.e. distance from the center of the merry-go-round). While the ball crosses the plane of the merry-go-round, any point of the plane has a tangential velocity which is, again, directly proportional to the radius, and thus, progressively decreases the closer the ball gets to the center. The greater tangential velocity of the ball, with respect to the points of the plane closer to the center of rotation, produces the fictitious acceleration to the right (since the merry-go-round is spinning counterclockwise, if it were rotating clockwise it would be to the left). It is the same force, for instance, that causes trade-winds.

It's pronounced the /ˌkôrēˈōləs iˌfekt/

It's simple: the ball was moving in the projected direction, but the catcher changed his location. This means the air on our earth's surface is moving in its projected direction. Rather, the location changes due to the earth's continuous rotation. And in the end, someone else gets the air.

When its inertial you can see it going straight but when its not inertial u can see the spin.

If she is watching from a non inertial frame of reference then shouldn't there also be a centrifugal force in radially outward direction ? And the net force would be resultant of centrifugal force and coriolis force ?

Makes sense. Look at a wall-clock and imagine you are located at 12;00. You throw a ball down to 6;00 (see it drop down that line). Only that it takes the ball 15 min. to reach down, AND the clock is also spinning CW by a quarter every 15 min. When the ball reaches all the way down you'll have 03;00 in that bottom position.

The ball didn't travel to the left! The ball moved in a straight line while the people moved underneath it, making it "appear" to travel to the left .It's why he said it's an "optical illusion".

Let's freak the girl totally out and spin the merry-go-round fast enough where she catches her own throw.

Vim pelo aero

isnt it just a net force that makes it go in diagonal direction? it had velocity vector perpendicular to the circle and a velocity vector of the throw

well, does it mean that the angular velocity of reference frame of the girl is not transferred to that ball, that's why it goes straight w.r.t ground ?

Wah

Did the machines running the matrix delete the guys "R" when he said Coriolis?! O_O

Well, technically anyone of the catchers or the thrower could have been in line to catch the ball depending on the speed at which the merry-go-round was spinning. I believe the people would be thrown off instantly if the person across from the thrower would have theoretically been able to catch it. :D It all depends on the speed of the rotation and time it takes the ball to reach a catcher going less than 6ft. The observed path caused the ball to make a 90-degree turn right from the thrower. Twice as fast of a spin you would have produced a 180-degree observed path back to the thrower. Four times as fast of a spin would give the ball an observed 360-degree curve and reach the original target who would have been thrown off instantly at around 67 or 135 miles per hour (assuming the merry-go-round is 6ft in diameter and rotated 360 degrees in between 1 and 0.5 seconds depending on the time it would take the ball to reach its destination) to his death position in .25 seconds falling one foot to the ground at a tangent distance of 24 to 50 meters away. : D

This video is not accurate. In the example they use, only the reference frame is changing because they're on a spinning object. They did not make any mention of the fact that differences in angular momentum are what actually cause this apparent force, not just a change in the reference frame. The angular momentum is equal in everyone's seat on a flat disc like they are, but on a sphere like the Earth it changes depending on latitude. When you move North or South, angular momentum is conserved, & because the Earth rotates at slower & slower speeds the farther away you move from the Equator THAT'S what causes the deflection we see as to the right in the Northern hemisphere & to the left in the Southern hemisphere.

I learned this in science class with Ms. Forgnoni at Atholton High School

What about the angular momentum of the ball ? Is it a factor ?

2:31 the animation is wrong for this experiment. since you are moving, you won't throw the ball straight if front of you, the direction you throw the ball is also combined with the direction in which you are moving. when you play basket you pass the ball straight to the guy who is running in the same direction for him to catch it. so it's not just the carry-holes effect at play.

Imagine the platform abruptly stopped exactly after the ball release. If they were moving fast enough, the person to the right would still catch the ball.
