Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.

No. The direction of motion changes all the time. Therefore, the velocity changes.

Is the velocity constant for an object in uniform circular and why?

The velocity of an object in uniform circular motion is constant, because, velocity is the rate of change of position at a given time or speed.


What are two ways in which an object can have constant velocity uniform motion?

Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.


What is the difference between uniform linear motion an uniform circular motion?

linear is which is on a straight path and circular motion is which has a curved path. *In a uniform linear motion,the velocity is constant and the acceleration is zero.So,uniform linear motion is an unaccelerated motion. *In uniform circular motion the velocity can be variable although the speed is uniform.So,it is an accelerated motion.


In uniform circular motion quantities are constant?

In uniform circular motion, what quantities are constant?


Can uniform velocity appear in circular motion?

No.. this is impossible. Velocity must have a constant direction and speed to remain constant, it may have a constant speed, but the direction in a circle constantly changes. If it suddenly were to have constant direction, then the motion would go off on a tangent.. making it linear motion, not circular. In circular motion, velocity constantly changes. Always.


What accelerates while traveling at constant velocity?

An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.


Is uniform circular motion and circular motion is the same?

no, in uniform circular motion the magnitude of your velocity, and therefore your acceleration is constant. in general this does not need to be true. consider this simple experiment, in a children's playground, go to a roundabout. stand on the roundabout and kick once, then wait for your motion to completely stop before kicking again. your motion is still circular, but neither velocity or acceleration is constant.


Is acceleration uniform in uniformly circular motion?

yes, acceleration is constant in uniform circular motion


Uniform and non-uniform motion?

if a body performs motion with constant speed along a circular path,its motion is called uniform circular motion. here,note that speed remains constant , not velocity. direction of velocity of a body in uniform circular motion, is different at each point on the circular path. consider a body performing uniform circular motion along the circle of radius'r' in anticlock wise direction. when this object is on points a,b,c,d and e, directions of its velocity are shown.v1=v2=v3=...v5=v v=distance travelled ----------------------- time =length of circular path ---------------------------- time v=circumference ----------------- time =2pier ------- t here v is also known as linear speed of the body performing uniform circular motion.


What is uniform circular motion?

Uniform circular motion describes motion in which an object moves with constant speed along a circular path.In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel. This changing velocity indicates the presence of an acceleration; this centripetal acceleration is of constant magnitude and directed at all times towards the axis of rotation. This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation.


Why tangential acceleration is not produced in uniform circular motion?

Because there is no tangential force acting on the object in uniform circular motion. The proof that there is no tangential component of acceleration is the fact that the tangential component of velocity is constant.


Why a circular motion is said to be uniform when the angular velocity is constant?

That's because that's precisely what "uniform" means: that something doesn't change.
