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 velocity of an object in uniform circular motion is not constant because although the speed may remain constant, the direction of the velocity continuously changes as the object moves along the circular path. This change in direction indicates a change in velocity, known as acceleration.

∙ 7y agoNo. The direction of motion changes all the time. Therefore, the velocity changes.

Can uniform velocity appear in circular motion?
No, uniform velocity cannot appear in circular motion because the direction of the velocity is constantly changing in circular motion due to the centripetal acceleration required to keep an object moving in a curved path. Uniform velocity implies constant speed and direction, which is not the case in circular motion.
Is the velocity constant for an object in uniform circular and why?
No, the velocity is not constant for an object in uniform circular motion because the direction of the velocity is changing continuously due to the object's changing direction as it moves along the circular path. The magnitude of the velocity (speed) remains constant, but the velocity vector is constantly changing direction.
What is the difference between uniform linear motion an uniform circular motion?
Uniform linear motion occurs when an object moves in a straight line with constant speed. Uniform circular motion, on the other hand, occurs when an object moves in a circle at a constant speed, where the direction of motion is constantly changing.
Why a circular motion is said to be uniform when the angular velocity is constant?
A circular motion is called uniform when the object travels around a fixed point at a constant angular velocity. This means that the speed and direction of the object remains constant throughout its motion, leading to a uniform circular movement.
In uniform circular motion quantities are constant?
In uniform circular motion, the speed of the object remains constant, but the velocity changes direction continuously. The acceleration is directed towards the center of the circle (centripetal acceleration) and its magnitude remains constant. The object moves in a circular path at a constant speed.

No, uniform velocity cannot appear in circular motion because the direction of the velocity is constantly changing in circular motion due to the centripetal acceleration required to keep an object moving in a curved path.

No, the velocity is not constant for an object in uniform circular motion because the direction of the velocity is changing continuously due to the object's changing direction as it moves along the circular path. The magnitude of the velocity (speed) remains constant, but the velocity vector is constantly changing direction.

In uniform circular motion quantities are constant?
In uniform circular motion, the speed of the object remains constant, but the velocity changes direction continuously. The acceleration is directed towards the center of the circle (centripetal acceleration) and its magnitude remains constant. The object moves in a circular path at a constant speed.
What are two ways in which an object can have constant velocity uniform motion?
An object can have constant velocity in uniform motion if it is moving in a straight line at a consistent speed. Another way is if the object is at rest, meaning it is not moving at all.
Is uniform circular motion and circular motion is the same?
No, uniform circular motion is a specific type of circular motion where the object moves at a constant speed along the circumference of a circle. Circular motion, on the other hand, refers to any motion that follows a circular path regardless of the speed or acceleration of the object. Uniform circular motion is a subset of circular motion.
Is acceleration uniform in uniformly circular motion?
No, acceleration is not uniform in uniformly circular motion. In uniformly circular motion, the direction of the velocity vector is constantly changing, which means there is always a centripetal acceleration acting towards the center of the circle. This centripetal acceleration is not constant in magnitude, making the overall acceleration not uniform.
Does motion of seconds hand of a watch represent uniform velocity?
No, the motion of the seconds hand of a watch is not an example of uniform velocity. The seconds hand moves in a circular motion at a constant speed, rather than moving in a straight line at a constant velocity. Uniform velocity refers to motion in a straight line with a constant speed.
What circular motion is one in which an oblect moves in a circular path at constant speed?
Uniform circular motion is when an object moves in a circular path at a constant speed. The object's velocity is constantly changing direction due to its circular motion, while its speed remains constant. This type of motion is an example of centripetal acceleration keeping the object moving in a circular path.
Why tangential acceleration is not produced in uniform circular motion?
In uniform circular motion, the speed of the object remains constant, so there is no change in the magnitude of the velocity. Since tangential acceleration is the rate of change of the magnitude of velocity, it is not produced in uniform circular motion. The only acceleration present is the centripetal acceleration which points towards the center of the circle.
Uniform linear motion vs uniform circular motion?
Uniform linear motion is when an object moves in a straight line at a constant speed, while uniform circular motion is when an object moves in a circle at a constant speed. In uniform linear motion, the velocity remains constant in both magnitude and direction, whereas in uniform circular motion, the object's velocity remains constant in magnitude but changes direction constantly.
