Why do very fast-moving wheels seem to move in reverse? - Quora.

The top is spinning in the same direction, but since the moment of mass has now changed (the top is on its side) it now spins in a new direction to counter the weight. I bet that didn't make one bit of sense, but it's the best I can do. It makes sense to me PC Lab Qmicra V2 Case SFF i7 950 4.4GHz 200 x 22 1.36 volts.

Why does a clockwise-spinning top suddenly spin... - Quora.

To know that this is conserved is enough to understand the motion of a wobbling spinning top! When the top is initially spinning fast, it is pointing straight up and rotating around that axis. Its. But why? Well, to a child, it is like watching anything that spins, the air around it is going to move in the direction of motion of the object spinning. Since the Earth moves or spins to the right, the strong winds that are experienced by a hurricane are typically moving in that same direction. Let's say the rock is curling to the left, so the right side is spinning "forward," and the left side is spinning "backward" as the rock moves down the ice. This means that the right side of the rock's running surface is moving forward faster than the left side is as the rock moves forward (in other words, the relative velocity is faster on the.

Why Are Spinning Reels Left Handed - The Angler Within.

Kung Fu Maintenance shows air conditioner fan spinning wrong direction how to change AC spin HVAC repair video.Get KFM's favored Multi-Meter here htt. The result is a flow pattern for the air outside the wake that looks like it's going over a wing, BUT right-side-up for back spin (lift) and upside down for top spin. The air outside the wake, follows this wing shape and has the expected pressure variation so that top-spin pushes the ball down (upside-down wing) and back-spin pushes it up.

The Physics of a Spinning Top - Futurism.

Answer (1 of 2): The phenomenon is caused by the fact that the top exhibits unstable rotation in other axes besides the one it's spinning in. As the top loses momentum in the key direction, and it falls over, the spin in one of the other directions can be transferred into the stable one. It sud. Or turn off the turntable in your microwave so nothing flies all over the place? You don't have to worry about any of that! Simply follow these 4 steps: 1) Press "Start" button. 2) Press "Stop" button. 3) Wait for microwave's timer to count down. 4) Press the "Turntable" button. Does a spinning object release a type of mass in the direction of the spin giving it angular momentum. (Explains why a fast moving top holds steady and a slower moving top wobbles, non-spinning top falls down) If so, if the mass released by the spin motion exceeds the amount of mass exerted by the gravity exerted on it, can it float?.

Why does a clockwise-spinning top suddenly spin counter... - Quora.

Collier N. Smith is a technical writer at Boulder Laboratories of the National Institute of Standards and Technology. Here is his reply. This phenomenon is not common in direct vision, but often. Why does a spinning top spin in the opposite direction when it. But why? Well, to a child, it is like watching anything that spins, the air around it is going to move in the direction of motion of the object spinning. A spinning ball or cylinder curving away from it’s principal flight path is called Magnus effect. The Magnus effect is named after Gustav Magnus, the German physicist who investigated it. In case of our example, the ball gets pulled upwards (because we are watching from top side). Actually, it is changing it’s path & following a curved one.

Why changing your ceiling fan direction matters and how to do it.

So when the top is spinning, and precession takes effect, the top will be learning some small amount, causing a torque and the precession will rotate the action of this torque 90 degrees. Well that causes the top to lean in a different direction, causing the rotation to act in a different direction, causing the top to lean in a different. Fight the fish with your stronger, more dominant hand. Having the reel handle on the left side frees up your dominant, and thus, stronger, hand to hold the rod. This is particularly helpful when you hook into a large fish. Your stronger arm can be used to work the rod on a large fish, while your weaker hand simply turns the reel handle. First you need to explain how the speed of points on a spinning object changes with distance from the axis of rotation. Imagine (or better, draw!) looking down on the spinning top from above, when it is spinning perfectly balanced. It turns at a certain speed, a number of turns per second. Now imagine a dot on the outer edge of the spinning top.

SPINNING TOPS - School of Physics.

A rapidly spinning top will precess in a direction determined by the torque exerted by its weight. The precession angular velocity is inversely proportional to the spin angular velocity, so that the precession is faster and more pronounced as the top slows down.

Why does a spinning top change direction.

Michael Pollick. Many people notice that the spinning rims of a car shown in a commercial or film appear to spin backward even though the car is clearly moving forwards. It is especially noticeable when the car is just beginning to speed up or slow down. During an extended shot of the car driving down an open highway, its spinning rims may even. This makes reversing your ceiling fan as simple as flipping a switch. Press the direction switch to set your ceiling fan to spin counterclockwise for the summer, and press the button in the opposite direction to set your fan to spin clockwise for the fall and winter. Remember to adjust your thermostat to take advantage of those energy savings. A spinning top precesses slowly around a vertical axis through its point of support while it spins rapidly about its own axis. The usual explanation is that the change in angular momentum must be in the same direction as the torque on the top – that is, in the sideways direction.

Why do Hurricanes spin the way they do? - Kids Science Labs.

The result is footage in which the wheel in question appears motionless: So when a wheel seems to spin in a direction opposite its actual rotation, it's because each spoke has come up a few. They are already changing direction around the spin axis, due the rigidity of the top keeping them moving in a circle. But gravity is operating at 90º to their direction of movement, and its effect depends on the velocity or inertia of the fragment. For a fast rotating top, this slight change of direction is what causes the top’s precession.

The basic physics of spinning tops - Scovie Precision Turning.

Seasons wouldn’t be affected much since presumably the speed of rotation would remain the same. 2. Wind patterns would change. The Earth has some pretty set wind patterns that result from the Earth’s spin. These winds would change direction, blowing eastward rather than west. The spin on the baseball is not confined to pitching. A ball hit to center field that would travel 350 feet with no spin will vary in distance depending upon the magnitude and direction of its spin. A graph of distance versus spin is shown below. The spin can change “a can of corn” to a pretty serious blast. Assume further that it is spinning with an initial velocity $\omega$ (assume the axis to be parallel to the surface of impact) and is dropped with no horizontal velocity. Upon impact, there will be a time interval $\Delta t$ during which the contact point cannot move (because of perfectly rough surface), but since the ball has an initial.

Why does a spinning top spin in the opposite direction when.

Blocking out the sun won't fix climate change - but it could buy us time; COP21 Discussion: Professor Kevin Anderson & Dr. Hugh Hunt - Climate Justice? "Let them eat cake!" SPICE - Stratospheric Particle Injection for Climate Engineering; Pipe-in-Pipe model for ground vibration from railways PiP TV, Radio and Popular Press. It all comes down to energy costs and comfort. Using ceiling fans can cut your energy costs by 4-8%, according to some estimates. The reason for the cost savings isn’t that a ceiling fan actually lowers or raises the temperature of a room, but instead, that the room feels cooler or warmer, allowing you to set your thermostat accordingly.

Q: What keeps spinning tops upright? - Ask a Mathematician.

Answer (1 of 30): When you record a video through a camera, it is recording in frames. This means at a very basic level that it is just capturing pictures really, really fast and then stitching them together. Now, when something is spinning so fast that in the time between taking pictures it turn. Right Before Your Eyes: The Science Behind The Famous Spinning Dancer Optical Illusion. At first glance, the spinning dancer looks just like an ordinary image of a woman doing a pirouette. However, for most, after enough observation, the tiny figure suddenly switches the direction of her dance. For over a decade this illusion has had viewers. The phenomenon is caused by the fact that the top exhibits unstable rotation in other axes besides the one it's spinning in. As the top loses momentum in the key direction, and it falls over, the spin in one of the other directions can be transferred into the stable one. It suddenly briefly rights itself.

How do you explain spinning tops to a nine year old?.

Answer (1 of 30): When you record a video through a camera, it is recording in frames. This means at a very basic level that it is just capturing pictures really, really fast and then stitching them together. The right hand rule. In order for a top to fall over its angular momentum needs to go from pointing vertically (either up or down, depending on which direction it’s spinning) to pointing sideways. So, in a cheating nutshell, tops stay upright because falling over violates angular momentum. Of course, it will eventually fall over due to torque. Curlers master the skill of judging the rotation and the path of the stone. They have the skill to place the stone where they want it. If the stone is not rotating, this level of control is lost. The scratches created by the leading edge can cause the stone to deviate to either left or right. The direction of the stone is less predictable.
