Top 10 reasons God does not exist - Random musings, rambling.

A spinning top is remarkable because it tends to defy gravity while it is spinning. If spun fast enough, a spinning top will rise to a vertical position and happily stay there, despite the fact that it will fall over if it stops spinning. A spinning egg is just as amazing. If a hard-boiled egg is spun fast enough it will rise up and spin on one.

Why does a spinning top balance better when it is spinning?.

Spin a top on a flat surface, and you will see it's top end slowly revolve about the vertical direction, a process called precession. As the spin of the top slows, you will see this precession get faster and faster. It then begins to bob up and down as it precesses, and finally falls over. Showing that the precession speed gets faster as the.

It’s crucial to note that ceiling fans don’t change the temperature; however, the blowing air can feel chilly—i.e., by changing your fan rotation to your desired direction. Why should you change your ceiling fan in winter and summer? Special Benefits of Using Ceiling Fan in Winter. Save heating costs up to 15%. Summary. Christmas cracker spinning top makes me think it should fall over. I took a spinning top out of a christmas cracker and watched it for a while. So I think a spinning top should just fall over like it does when it is at rest. Why does it "work"? It balances better when you spin it on its axis. 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.

Q: Why does putting spin on a ball change how it moves through the air.

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.

Precession of Spinning Top - Georgia State University.

Jul 12, 2021 · So whichever position you feel the most air movement when standing directly under the fan is the correct position for summer. If you do not feel much air in either direction, then your fan has a very weak motor with a relatively flat pitch to the blade. Fans like this won't do much good for you in either direction during the summer.

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

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. 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. 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.

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. Spin an object like a child's top on it's "point". The top is spinning in this direction ---> around it's center. Sometimes, when it spins down enough that a part of the object touches the surface it's spinning on, the top suddenly spins in the opposite direction in a circle (that way<----) around the point.

Press J to jump to the feed. Press question mark to learn the rest of the keyboard shortcuts. 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. Answer (1 of 3): Well, don't take it the wrong way, but you've asked a bit of a mish mash of a question, so, I'll try and separate the bits, and put it back together in a more cohesive manner. First off, let's separate the question into bite size pieces, like this... What are the differences a.

Electric Motor Rotation Direction, Which way does an electric.

Look at the vines holding onto the lattice. The "vine springs" change their spinning direction in the middle. Why? And how do they achieve this? (By the way, what's the name for this plant? Is is correct to call these "springs" vines?) Edit: I notice that some vines fail to get in touch with the lattice, in such case they still change direction.

What does cross(x) or a dot (.) Mean interms of current.

The individual pictures do not actually move. Instead, the position of a moving object shifts with respect to the background in each successive still frame; when viewed rapidly, one gets an. 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.

This spinning is connected to a generator, which produces the electricity. That’s all you really need to know, but if you’re interested in the technical terms, these same elements are called a mast, a nacelle and a rotor. The mast supports the rotor and nacelle, and the nacelle contains the mechanical parts. Answer (1 of 16): > These sign. shows the direction of magnetic field due to current perpendicular to plane of paper. When a current flows through a conductor, it produces a magnetic field, shown in the above diagram as the green circular arrows surrounding the wire. Since most of the weight in a top is usually at the base (most 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.

Why don't spinning tops fall over? - Physics Stack Exchange.

Sep 06, 2016 · Does it? Why? Demonstrate that life was created, please. (3) design demands a Designer. Yes, if something was designed. If we’re talking about the universe, we don’t know it was. First show something was designed, then you can make this claim. (4) intelligence demands an Intelligent Creator. Does it? Why? Show that this is demonstrably true. 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. When the top is spinning fast a slow rate of precession is enough to provide sufficient torque in the direction that sustains fairly upright orientation. As the spinning top slows down a larger rate of precession is required to provide the same amount of upright-maintaining torque. Increase of rate of precession goes at the expense of height.
