for centripetal acceleration, a=(v2)/r

where v = the tangential speed and r = radius of the circle.

c = 2r * pi

r= c/(2*pi)

a=(v2)/(c/(2*pi))

a=(2*pi*v2)/c

a=(2*3.141592...*(8.12))/200

a= 2.06 ms-2

If an object is moving in a circle with a constant speed Its acceleration is constant in what?

If an object is moving in a circle with a constant speed, its acceleration is directed towards the center of the circle and is constant in magnitude. This acceleration is called centripetal acceleration and is required to keep the object moving in a circular path.


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.


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.


Is it possible that the velocity of a body changes and its acceleration remains constant?

The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.


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.

Does the speed of a car moving in a circular path at 15 mph remain constant Or does the acceleration or its velocity remains constant?

The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle


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.


Can a body have 0 velocity and still acceleration?

Yes, a body can have zero velocity and still have acceleration if its speed changes directions while its magnitude remains constant. This situation occurs when an object is moving in a circular path at a constant speed. The change in direction of velocity due to the circular motion results in centripetal acceleration.


How is circular motion accelerated motion?

"Acceleration" means a change in velocity. And "velocity" is a vector - meaning that not only the magnitude, but also the direction is relevant. So, if the direction of the movement changes, the velocity changes by definition, even if the MAGNITUDE of the velocity (also known as "speed") doesn't change.


What remain constant in uniform circular motion?

In uniform circular motion, the speed of the object remains constant as it moves around the circle. However, the velocity of the object changes because the direction of the velocity vector is constantly changing. The centripetal acceleration remains constant in magnitude and always points towards the center of the circle.


Can an object acceleration if its velocity is constant?

No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
