What does the linear speed of a rotating object depend on?
The linear speed of a rotating object depends on its angular speed (how fast it rotates) and the distance from the axis of rotation (the radius). Linear speed is calculated as the product of the angular speed and the radius.
How do you convert linear speed to angular speed?
To convert linear speed to angular speed, divide the linear speed by the radius of the rotating object. The formula for this relationship is: angular speed (ω) = linear speed (v) / radius (r). This will give you the angular speed in radians per second.
Why Do you need to balance the rear wheels?
If wheels aren't balanced they'll vibrate when they're rotating at speed. This can be unpleasant and can even increase wear on tires and suspension.
How is rpm related to speed?
More rpm means more speed, but the speed is also related to the diameter of the rotating object. The exact formula is: speed = angular speed x radius (assuming compatible units are used: for example, speed in meters/second, angular speed in expressed in radians/second, radius in meters).
What is the linear speed of a bicycle that has wheels with a 2m circumference when its wheels rotate at 1 revolution per second?
2 meter circumference rotating 1 revolution per second produces a linear speedof 2 meters per second.The question can be slightly more exciting if you give the diameter of the wheel,or even its radius, instead of its circumference.
What is the speed you read from your speedometer called?
The speed you read from your speedometer is called your "indicated speed." This value represents the speed at which your vehicle's wheels are rotating, not necessarily your true ground speed due to potential inaccuracies in the speedometer reading.
What keeps water in a rotating bucket from falling out?
Centripetal force. The water wants to fall out due to gravity, but the speed of the rotating bucket cancels it out, creating an inward acceleration.. It is the same as why you don't fall out of an upside sown roller coaster. The speed has to such to cancel out gravity acceleration, where velocity squared divided by the radius of the rotating circle is the acceleration of gravity
How do you know that a speedometer tells you the instantaneous speed of a car?
Because when you look at the speedometer it is telling you your speed at that particular instant in time, it changes from instant to instant.
What is the speed of low speed flywheel?
Generally, flywheels used for energy storage are divided into high-speed low-mass wheels rotating at 50,000 rpm and above and are typified by magnetic bearings and relatively small mass wheels (usually woven polymer fiber) measuring about 20-24 inches in diameter. Low-speed high-mass flywheels rotate at between 5-7,000 rpm and are typified by high mass solid wheels (steel and/or high-density alloys with diameters of several feet) supported by conventional tapered roller bearings.

How do you change the speed without changing the angular momentum?
To change the speed without changing the angular momentum, you can change the radius of the rotating object. This is because angular momentum is the product of an object's moment of inertia, its mass, and its angular velocity. By adjusting the radius while keeping the other factors constant, you can alter the speed without affecting the angular momentum.
What is the schwarzschild radius of earth?
The schwarzschild radius of the Earth is about 8.7 x 10 to the negative 3m. The schwarzschild radius is the radis of a sphere that is around a non-rotating blackhole. You find the Rs, or radis, by multiplying the gravitational constant(G), the mass(M), and two. You divide this by the speed of light(c) squared.
How is the centripetal force on a rotating body affected if you double the radius and leave the tangential velocity the same?
If you double the radius while keeping the tangential velocity constant, the centripetal force will also double. This is because the centripetal force is directly proportional to the square of the velocity and inversely proportional to the radius. Therefore, doubling the radius increases the centripetal force required to keep the body rotating at the same speed.
