In circular motion an object accelerates towards the radius of the circle but its velocity is unchanged
Centripetal means towards the center. Any object moving around in a circle is accelerating towards the center. Remember that acceleration involves a change in velocity, and a specification of "velocity" includes the direction; therefore, since the direction of the movement changes continuously, the object is "accelerating", according to the definition of acceleration.
A motion is simple harmonic if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean position.
As the ball moves in a circular path, it changes it's direction every moment. velocity is a vector and it depends both on speed and its direction. So, as the ball is changing its direction every time, we can say that it is changing its velocity as well. So, the ball is actually accelarating
No! Carousels move in a circle (at least all the carousels I know do) in circular motion there is constant acceleration directed towards the center of the circle of magnitude a=v2/r
The unit of centripetal acceleration is meters per second squared (m/s^2). It represents the change in velocity per unit time in the direction towards the center of the circular motion.
The acceleration of a satellite is directed inward, towards the center of the orbit.
It will measure acceleration in the direction towards or away from the origin.
Yes. Since the velocity changes all the time, there is an acceleration. The acceleration is towards the center of the Earth. Note that the speed need not change; velocity consists of a speed (magnitude) and a direction, and in a circular orbit, it is the direction that changes.Yes.

The velocity in a circular orbit changes all the time. The acceleration is towards the center.
No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal acceleration is zero. However, this would only exist for that small instant in time.
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.

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
Answer Both refer to an object that is in a cirular motion. Radial Acceleration is a velocity change of the object as it moves away from the center of rotation. Tangential Velocity is a change of velocity of the object as it moves in a line that is tangential to the circular path it is moving.
A motion is simple harmonic if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean position.
Acceleration is negative if velocity is decreasing with time. Since velocity is a vector this can occur in one of two ways: 1) you are slowing down in the direction of motion and the velocity in that direction is defined as positive (this is what we usually mean by negative acceleration) 2) you are speeding up in the direction of motion and the velocity in that direction is defined as negative. An example of this is an object launched into the air which immediately starts to decelerate in it's upward velocity, reaches it's highest velocity, and then begins accelerating towards the ground. If we call the velocity upward a positive velocity, then when it starts falling, it has negative velocity. Note that acceleration (due to gravity) is negative the whole time.
As the ball moves in a circular path, it changes it's direction every moment. velocity is a vector and it depends both on speed and its direction. So, as the ball is changing its direction every time, we can say that it is changing its velocity as well. So, the ball is actually accelarating
