Why is a particle in uniform circular motion not moving at a constant velocity?

No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing.
Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.

∙ 13y agoObjects do not remain in constant motion because of newton's 2nd law of motion: objects in motion remain in motion forever unless acted upon by an outside force. Therefore, objects do not remain in motion because they have been acted upon by and outside force ( balanced force ).

and anything in circular motion is constantly changing direction.

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 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.
If displacement of a particle is zero?
If displacement of a particle is zero in a uniform circular motion, then the distance travelled by that particle is not zero, kinetic energy is constant, speed is constant and work done is zero
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.

What factors affect the increase of the centripetal force on a particle in uniform circular motion?
The centripetal force on a particle in uniform circular motion increases with an increase in the mass of the particle or the speed at which it is moving. It also increases if the radius of the circle decreases, as the force required to keep the particle in the circular path becomes greater when the circle is smaller.

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.
Does velocity of an object remain constant in uniform circular motion?
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.
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.
In uniform circular motion quantities are constant?
In uniform circular motion, what quantities are constant?
Is Accelerated is related to the statement Circular motion with uniform speed?
yes.acceleration means change of velocity and not speed to be more precise.in a circular motion with constant speed the particle or the object constantly changes its direction.the direction of velocity is directed along the direction of the tangent at that point.although speed remains constant the velocity changes infinite number of times.so the particle is said to be accelerating.there is always instantaenous acceleration.but the average acceleration becomes zero after every round because velocity becomes the same after every round.
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.
