Applied Physics: Why does a top stand up when spinning?.
Since most of the weight in a top is usually at the basemost of the weight below the largest diameter, the top will spin counter clockwise because of the weight being thrown outwards. This is difficult to explain, sorry haha. It's really an illusion, the top isn't actually spinning the opposite direction, quite the opposite. The top is spinning in the same direction, but since. Answer 1 of 3: Well, don#x27;t take it the wrong way, but you#x27;ve asked a bit of a mish mash of a question, so, I#x27;ll try and separate the bits, and put it back together in a more cohesive manner. First off, let#x27;s separate the question into bite size pieces, like this... What are the differences a. 1 Answer Sorted by: 6 It is a matter of control over the stone#x27;s path. A rotating stone creates small scratches in the ice with its leading edge, which cause the trailing edge to change direction as it crosses them. This gives the curved path. Explained in this PhysOrg article, which also contains links to other explanations.
Why do Spinning Rims Appear to be Rotating Backward?.
Why does a spinning top flip over? At first glance, a Tippe Top looks like a normal spinning top. The friction with the table applies a torque that causes the top to tip over, changing its angular momentum. When it becomes horizontal, the top actually reverses its direction of spin! Once the stem hits the table, the torque causes the top to. 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#x27;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. 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.
Right Before Your Eyes: The Science Behind The Famous Spinning Dancer.
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. The effect occurs due to the 60 cycle per second flickering of the light, which is normally too rapid for the eye to register. When the blade interval and frame interval are quite different from.
Why does a spinning top get back upright when knocked?.
At the moment you spin the ball, the forward force is greater then that of the backspin, so the ball moves away. After time zero, the backspin is the only force acting horizontally you aren't still touching the ball, so there is no applied force and so the ball slows, then returns because of a negative acceleration. The air velocity RELATIVE TO THE SPINNING BALL is higher on the side spinning into the flow, e.g., on top for top spin. This causes the turbulent boundary layer insured by the rough surface to separate earlier on that side than the other. This causes the turbulent wake to move around in the direction of rotation upward for top spin, downward for back spin. The. The quick answer is that, for the top to fall over due to gravity, each fragment of the top that is moving around the spin axis has to change its individual direction of movement. 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 90#186; to their direction of movement, and its effect depends on.

Classical mechanics - Why does a ping pong ball change direction.
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 appear to stand still and then rotate backward. There are actually several different optical illusions at work which cause spinning rims to appear to spin in reverse.
Why don't spinning tops fall over? - Physics Stack Exchange.
Spinning top becomes almost upright again because it has angular momentum and that means that if an object spins it is resisting its axis of rotation to be precessed and faster it spins more it is resisting this precession to occur so if i tipped it over if it still spins with same angular velocity it will return to zero precession, faster it. Gravity causes a torque that trys to rotate the top more and more in the direction it is already leaning. 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. According to the researchers#x27; hypothesis, our inclination to view the dancer as spinning clockwise is due to our quot;visual systems preference for viewpoints from above rather than from below,quot; the authors wrote. In their research, they found that when they altered the GIF to be viewed from different camera angles, the viewer#x27;s perception shifted.

At a certain point, the spin of the wheels appears to slow, slow, slow. Then, ever so briefly, it stops. When it resumes, the spin is in the opposite direction. By appearance, the car should be.
Electric Motor Rotation Direction, Which way does an electric motor.
A spinning top remains upright for the duration of the spin because the speed causes atmospheric ambient affect the top as if the top is perfectly spherical or circular. The speed cancels out all minor imperfections in the shape and/or composition of the the faster the top spins, the more its imperfections are cancelled out. Usually, the torque acting on a spinning top is just due to the weight of the top. If the top is perfectly upright there is no torque acting on it but if it leans sideways then it will tend to fall over due to the torque about the bottom end. It will.

Now according to Bernoulli#x27;s principle, at the top side of the ball, due to high velocity a low pressure region gets created. This low pressure region pulls the ball with certain force - Magnus force. A spinning ball or cylinder curving away from it#x27;s principal flight path is called Magnus effect. 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. 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 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. 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. In sum, the combination of a load or rotation resistance provided by the turntable mechanism and an automatic direction reversing feature in the electric motor gets the microwave motor spinning and the turntable rotating - which is why each time you start your microwave it is likely to rotate in the opposite direction from that of its previous. The explanations I#x27;m familiar with is that the quasi-liquid layer is mainly responsible for reducing friction, and this layer affects the front of the stone more than the back, because the contact pressure of a 42 pound stone will increase the thickness of that layer. This makes any friction at the back dominate over that of the front.
Q amp; A: Spinning objects releasing mass? | Department of Physics.
Wind turbine rotor blades can be designed to spin in either a clockwise or counterclockwise direction to generate electricity. Because of simplicity and a single global standard, most turbines rotate in a clockwise direction. When two or more wind turbines are situated one behind the other, the rotor spin direction may make a difference.

How a top falls. As a spinning top slows and gravitational torque comes into play, the tops angular momentum decreases. When it loses enough angular momentum, it falls. The decrease in angular momentum creates a phenomenon known as precession. This is a change in the orientation of a spinning object, causing it to spin around a secondary axis. With spinning tops,..
