# What is angular speed and angular velocity?

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 / tim…e), 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. (MORE)

# What is angular velocity and radial velocity?

Angular velocity is the rate of change of angle of a body, i.e. omega = v / r = (2*pi*r)/ r*t = (2*pi)/ T where T is the time period of whatever is rotating and r is the ra…dius of the circle.So if a circular disc is spinning at 1 m/s then the angular velocity of it is 2*pi radians/ second Radial velocity is the velocity in m/s at the radius of the circle i.e. radial velocity v = omega*r = (2*pi*r)/ T (equivalent to speed = distance/ time where in this case distance is the circumference of the circle and time is the time period of one rotation)----------------------------------------------------------------------------------------------------Angular velocity Ï‰, is the rate of change of angular displacement dÏ†/dt. Itspecifies the angular speed (rotational speed) of an object and the axis about which the object is rotating. Ï‰ = 2Ï€f =2Ï€/T [=] rad/s where f is the rotation frequency (rev/s) and T the time it takes to make a revolution (s/rev). Tangential velocity v. When an object rotates around in a circle with radius r, itslinear velocity tangent to the circle is the tangent velocity v. v = Ï‰r [=] m/s Radial velocity vr, is the component of the velocity of an object away or towardthe origin or point of observation.

# How do you define angular velocity and angular speed?

Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only…. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise). (MORE)

# Burner Designs on Electric Smoothtop Cooktops and Ranges

Every burner on smoothtop [electric cooktops](http://www.houseware.answers.com/appliances/what-are-built-in-electric-cooktops) and ranges are the same, right? The answer is n…o and it's the difference in burner designs that contributes to the price point of a specific cooktop or range. This article will explain the various burner configurations of smoothtop, sometimes referred to as glass-top, cooking appliances.Outlined by an etched circle on the glass, radiant burners are measured in inches by their diameter. Burners measure as little as 5-inches across while larger ones reach 13-inches. Not every burner on a specific cooktop is the same; rather various sizes exist to accommodate various sizes of pots and pans. Keep in mind that the number of burners is directly connected to the width of the appliance. Cooktops and ranges in the 30-inch width category usually feature four, sometimes five, burners. Smaller 12-inch cooktops have two burners, one in front of the other. Wider 36-inch models feature five, sometimes six, burners. Radiant burners are the basis for the next burner designs.Marked by additional circles within a radiant burner, dual- and tri-ring burners offer flexibility because their diameter can adjust to match, as close as possible, the diameter of a particular pot or pan. This is accomplished by utilizing the dual- or tri-ring setting on the touch panel or knob controls, depending on the model, which in turn activates additional heating elements below the glass. Naturally dual ring burners offer two possible diameters and tri-rings burners offer three possible diameters. Though this burner design is reserved for upgraded models, certain units feature more than one dual- or tri-ring option.Adding to the flexibility of certain cooktops and ranges are bridge burners. The concept behind a bridge burner is to connect two burners, either front to back or side to side, to create a larger, oblong shaped burner. This is accomplished by activating a heating element between the two radiant burners. Bridge burners are designed to accommodate roast pans; griddles; or other oblong cooking vessels. Additional etching outlines the area on the glass between the two radiant burners denoting the bridge burner.Certain cooktops and ranges feature a warming zone that looks just like radiant burner. Warming zones; however, do not reach temperatures suitable for cooking. Instead they, as their name suggests, are designed to hold items after cooking like soups, stews, and sauces.The Schott Corporation provides many appliance manufacturers with the glass for their smoothtop cooktops and ranges. Schott also manufactured the glass for the lenses in the cameras that filmed Neil Armstrong and Buzz Aldrin's moon landing.Though smoothtop cooktops and ranges might look the same at first glance, the various burner designs contained within each model helps to separate one unit from another and directly affects the price of a particular unit. Smoothtop appliances provide easy clean up because of their glass surface and their various burner designs from varying diameters to bridge burners and warming zones offer flexibility for your cooking needs.

# When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?

Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they …are in opposite direction. It does not matter if the motion in linear or anfular. (MORE)

# What the relationship between angular velocity and period of rotation?

The time, T , it takes for an object to go thru one comblete rotation of 360 degrees or 2pi radians is its "period." The rate at which it completes the rotation is its "an…gular velocity." The rate is the angle (in radians) divided by the time. So , Angular Velocity = 2 pi / T. (MORE)
