Q: Question about linear speed and angular speed?

Write your answer...

divide the linear speed by the radius

Linear speed is the speed of an object along its path of motion. Angular speed is how fast an object is changing its angle (rotating) about an axis.

No. Acceleration and speed are related in the same way irrespective of being linear or angular. Acceleration is rate of change of speed.

v=w*r v-linear speed w-angular(rotatinal) speed r-objects radius

For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.

The linear (tangential) speed of a point on a spinning circle is(angular speed of the spin) x (radius of the circle). Note that this only works if the angular speed is in units of radians/time .To convert degrees to radians, multiply by (pi)/180 ... about 0.01745 .

That is analogous to linear speed and velocity, but for rotation. Whereas a linear speed (or velocity) is expressed in meters per second (or some other units of distance / time), the angular speed or velocity is expressed in radians / second (or some other units of angle / time). Of course, when something rotates, there is also a linear speed, but different parts of an object rotate at different linear speeds, whereas the angular speed is the same for all parts of a rotating object - at least, in the case of a solid object. For example: the Earth rotates at an angular speed of 1 full rotation / day. The linear speed at the equator is approximately 1667 km/hour; close to the poles, the linear speed is much less.

A planet has an elliptical shaped orbit. It orbits with a constant angular speed, but a varying linear speed.

Angular velocity means how fast something rotates. The exact definition of angular momentum is a bit more complicated, but it is the rotational equivalent of linear momentum. It is the product of moment of inertia and angular speed.

linear acceleration = radius * angular acceleration

linear velocity= radius* angular velocity

In the case of circular motion - an object can have constant angular speed and experience constant linear acceleration.

angular mmtm is a cross product unlike linear momentum

linear velocity is a change of speed in a linear fashion. Angular speed is the rate of change of angle with respect to time. These two are convertible in a case of a circle motion. the lenght of an arc is l = RO. where O is the angle. hence v= l/t and therefore v=RA where A = O/t.

Angular velocity is a vector with a direction and angular speed is a scalar with no direction.

The moment of linear momentum is called angular momentum. or The vector product of position vector and linear momentum is called angular momentum.

I believe that any particle in linear motion must also have some angular momentum because all particles have spin. In the case of a photon the spin, wavelength and angular momentum all vary with the relative linear velocity. So in my point of view time itself is the ratio between relative linear and angular momentum.

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?"

Angular momentum is defined as the moment of linear momentum about an axis. So if the component of linear momentum is along the radius vector then its moment will be zero. So radial component will not contribute to angular momentum

if the angular speed of an object increase its angular momentum will also increase

velosity in circular path angular

v=Wr w=angular speed

The angular speed of Earth's rotation is 15o per hour. The linear speed at the equator is just over 1000 miles per hour.

There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.

angular momentum = linear momentum (of object) x perpendicular distance (from origin to the object) where x stands for cross product. angular momentum = mv x r (perpendicular dist.)
