In circular motion the acceleration is towards the center but why does not the ball moves towards the center?

As strange as it may seem at first, the ball is actually moving towards the center, its just that when the centripetal force pulls the ball towards the center, the objects preexisting speed moves it to another spot on the circle, stopping it from actually spiraling inwards.
One way to visualize this is to imagine that you throw a ball. Under normal circustance, when you throw the ball, it will go forward for a little bit but it will eventually be pulled down by gravity and hit the ground. Now, imagine that you could throw the ball so fast that by the time it falls 10 feet, it has gone far enough out form the Earth that there is another 10 feet to go before it reaches the ground. Thus, even though the ball is getting pulled towards the Earth, its falling as fast as its moving.
Its this combination of falling and moving that actually creates the circular motion. If the falling is faster than the moving, the object will just eventually spiral into whatever is pulling on it. Alternatively, if the moving is faster than the pulling, there will be an overall hyperbolic path, as the object gets close to the source of the pul but then shoots away.

Is the statement 'a body moving with uniform speed along a circular path is subjected to uniform acceleration' true or false justify?
This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.
Is the fan an example of circular motion?
yes, a fan is an example of a circular motion
What is the acceleration of an object at a given time?
A particle moving with a constant velocity has no acceleration. Acceleration is the change in velocity over time. If the velocity is constant, there can be no acceleration. For you Calculus junkies, dv/dt (v is velocity) is acceleration, and will equal zero if v is a constant.
How circular motion and variable motion alike?
Circular motion and variable motion are alike because both of them are constant. Another way they're alike is that variable motion is used with transportation movements like cars, trucks, and buses. Circular motion can also be used with transportation like with wheels on cars, trucks, and buses.
Why do winds spiral towards the center of the hurricane?
Winds move toward the center of a hurricane because of the low pressure generated by the upward motion of the air inside it.
What is the direction of acceleration in circular uniform motion?
Towards the center of the motion.
What is needed for circular motion?
For circular movement, you need a force that pulls an object towards the center of the motion. This is a consequence of Newton's Second Law, since circular movement implies acceleration towards the center.
What is the direction of the acceleration vector of a person on spinning earth?
The acceleration vector in a uniform circular motion is towards the center.
Why is circular motion an example of constant acceleration?
Actually it isn't. In circular motion, even if you assume a constant speed (the simplest case), acceleration is towards the center. Therefore, the direction of the acceleration changes all the time - and therefore, the acceleration changes all the time.
What is acceleration that occurs in a circular motion?
Acceleration in circular motion is the acceleration directed towards the center of the circle, known as centripetal acceleration. It is responsible for keeping an object moving in a circular path rather than in a straight line. The magnitude of centripetal acceleration is given by the formula a = v^2 / r, where v is the velocity of the object and r is the radius of the circle.
Why a body moves in a circular motion?
A body will move in circular motion if there is a force to accelerate it towards the center.

For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.
Is acceleration uniform in uniformly circular motion?
yes, acceleration is constant in uniform circular motion
Do centripetal forces act by pushing an object towards or away from the center of circular motion?
Towards!
What is centripital acceleration?
acceleration in a circular motion :)
What is the unit of centripetal acceleration?
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.
Will a child on a carousel moving at constant speed has an acceleration of zero?
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
