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.

Is it true or false that For a particle in uniform circular motion the instantaneous-acceleration vector is directed radially outward?

True. In uniform circular motion, the particle's velocity is tangential to the circular path, and the acceleration is directed radially inward, towards the center of the circular path. This centripetal acceleration causes the change in direction of the particle's velocity, but the magnitude of the velocity remains constant.


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.


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

Are you talking about the Illinois Particle accelerator? Well I think that it doesn't go at a constant speed but at a constant Acceleration, since it is accelerating and not staying at one speed is is therefor Constant Acceleration until they slowly work it up to almost the speed of light.


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.


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.

What factors affect the increase of the centripetal force on a particle in uniform circular motion?

Increase in radius affect the increase of the centripetal force on a particle in uniform circular motion. An increase in radius would cause a decrease in the force if velocity remains constant.

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.


Does velocity of an object remain constant in uniform circular motion?

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.


Is it true or false that For a particle undergoing uniform circular motion the instantaneous-acceleration vector equals zero.?

False. In uniform circular motion, the instantaneous acceleration is directed towards the center of the circle, which is called the centripetal acceleration. This acceleration is responsible for changing the direction of the velocity of the particle, even though its speed remains constant.


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.


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.
