In uniform circular motion only a radial component of acceleration is present i.e centripetal acceleration. So why doesn't the particle following uniform circular motion go radially inwards due to radial acceleration?
Lets draw a rough sketch.First draw a circle.Then draw a velocity vector(tangential) at time t.Add acceleration vector(radial).Where do you see the resultant velocity? Is it towards the centre or somewhere tangential to the circle ?andyrk said:I
mean to say that
if the net force of the particle is radially inward then why doesn't
the particle move radially inwards? Thanks for the previous reply though
:)

to pinpoint,
but how can we add acceleration vector to velocity vector? Isn't vector
addition of only like quantities allowed?

By definition, if the particle is uniform circular motion, then it's combination of speed and acceleration result in a circular path.andyrk said:In uniform circular motion only a radial component of acceleration is present i.e centripetal acceleration.

Uniform circular motion is a type of motion in which an object moves along a circular path at a constant speed. This means that the object's velocity is constantly changing due to the change in direction, but its speed remains the same.
The main difference between uniform and non-uniform circular motion is that in uniform circular motion, the speed remains constant while the direction changes, whereas in non-uniform circular motion, both the speed and direction are constantly changing.
The centripetal force is the force that keeps an object moving in a circular path. In uniform circular motion, the centripetal force is directed towards the center of the circle and is responsible for constantly changing the direction of the object's velocity.
Uniform circular motion is a special case of rotational motion, where an object is rotating around an axis at a constant speed. In both cases, the object's velocity is constantly changing, but the speed remains the same.
Tangential speed refers to the speed of an object along its circular path, while angular speed refers to the rate at which the object's angle changes as it moves along the circle. Tangential speed is measured in units of distance per time, while angular speed is measured in units of angle per time.
