Why does angular speeds stay the same even though the linear speeds are different?

because god said it shouild
Think of a stone on a string whirling around, two complete turns per second. Suppose the angle that any part of the string, or stone, rotates through is 2x360 degrees per second (=angular spesd). But the stone might be going at 10 feet per second (=linear speed), at the same time that the bit of string 2 inches from your hand is going less than 1 foot per second (linear speed), while the angular speed is still 720 degrees per second. Angular speeds and linear speeds do not even have the same Dimensions: 1/T vs L/T. The question ought to be "why should anyone think these things to be the same?"

How can your speed accelerate even though your speed does not change?
By moving in an angular motion.
How would the angular separation of interferences fringes in young's double slit experiment change when the distance of separation between the slits and the screen is doubled?
Note that bandwidth = lamda D / d and bandwidth = D @ Here @ is the angular separation. So @ = lamda D / D d = lambda / d So as D is not there in the expression the angular separation remains the same though the distance between slits and the screen is doubled.
Does the same wave travel at different speeds in different mediums?
Short Answer:The speed of a wave depends very much on the type of the wave and the medium though which it moves.More:Sound waves in air, water waves in the ocean and light waves in space are waves different waves in different mediums and with vastly different speeds. Each of these types of waves changes speed dramatically in different media. Ripples move at a different speed than ocean waves. Light in glass travels at about two thirds of the speed of light in a vacuum and sound waves in metal are much faster than sound waves in air. Another good example is waves from an earthquake, which occur in two different forms and which are regularly experienced as separate shocks from an earthquake.
Do sound waves of different frequencies travel at different speeds?
No, light is slowed depending on what medium it travels through. That's why we have the constant ' c ', defined as the speed of light 'in a vacuum'. The actual speed light travels through air, glass, jello, or water, is less than 'c'.
How can an object moving at a constant speed have a nonzero acceleration?
Let's review some terms before we tackle this one. Speed is displacement per unit of time. We know 60 miles per hour is a speed. Velocity is speed with a direction vector associated with it. We know 60 miles per hour east is velocity. Acceleration is a change in velocity. That means if an object changes its speed or its direction or both, it is accelerating.If an object has a given velocity and it slows down or speeds up, it is accelerated. But if the same object changes direction without a change in speed, it is still experiencing acceleration. A force had to act on the object to change its direction, even though its speed didn't change. Thus, an object can accelerate even though it does not change speed.
Do other planets in your solar system rotate as the earth does?
Yes, all of them do, though at different speeds.
Why do moons take different times to orbit Jupiter?
Because, by Kepler's laws of motion, they have to go different speeds to maintain their orbits, and though they also have different distances to go because they are different distances from the planet, the speeds are so different that they take different amounts of time to orbit the planet.
How can your speed accelerate even though your speed does not change?
By moving in an angular motion.
What is the meaning of Correlations?
It means that here is no linear relationship between the two variables. There may be a perfect non-linear relationship, though.
What is the meaning of no correlation?
It means that here is no linear relationship between the two variables. There may be a perfect non-linear relationship, though.
Is enzyme when a chemicals reaction speeds up?
No, that is a catalyst. An enzyme is a type of catalyst, though.
What types of problems will happen if you damage your angular gyrus?
Angular gyrus is the Brodmann's Area 39 and is commonly known as part of the Wernicke's area. This gyrus is responsbile for understanding written language. So, any damages to angular gyrus of your dominant hemisphere might result in "alexia" (loss the ability to understand the meaning of what you read, though you can see the words)
Is an ice molecule linear?
Technically, yes but literally no. even though the ice linear is moleculetic it is within no range of ice atom bombs such as ak 47
What are the ways of finding the linear functions?
A linear function can be determined simply from its form. A linear function, over a set of variables, x1, x2, x3, etc is of the form a1x1 + a2x2 + a3x3 + ... = b where a1, a2, a3, etc and b are constants. In graphical terms the linear function over n variables is a straight line in n-dimensional space. In 2-d different letter are used instead of subscripts and the equation becomes ax + by = c This can easily be shown to be equivalent to y = mx + c (though with a different value for c).
What is a ratio of 2 measurements having different units?
It can be a conversion factor - though not necessarily. For example, 68 deg Fahrenheit = 20 deg Celsius. But there is no conversion factor for F-to-C: instead there is a linear equation.
What is average velocity in science?
If it takes an object a certain amount of time to travel a certain distance, but it is travelling at different speeds at different times, you can treat it as though it was travelling at the same speed all the time, and then just divide distance by time to get speed (for example, in miles per hour).
How would the angular separation of interferences fringes in young's double slit experiment change when the distance of separation between the slits and the screen is doubled?
Note that bandwidth = lamda D / d and bandwidth = D @ Here @ is the angular separation. So @ = lamda D / D d = lambda / d So as D is not there in the expression the angular separation remains the same though the distance between slits and the screen is doubled.
