Non uniform circular motion refers to the movement of an object along a circular path at varying speeds. This means that the object is not moving at a constant speed, but instead its velocity changes as it moves around the circle.
Non uniform circular motion is caused by a combination of two forces: the centripetal force, which pulls the object towards the center of the circle, and the tangential force, which acts in the direction of motion and causes the object's speed to change.
The normal acceleration in non uniform circular motion refers to the component of acceleration that is perpendicular to the object's velocity. It is equal to the square of the object's speed divided by the radius of the circle.
The formula for calculating normal acceleration in non uniform circular motion is a = v^2/r, where a is the acceleration, v is the speed, and r is the radius of the circle.
Yes, the normal acceleration in non uniform circular motion changes because the speed and direction of the object's motion are constantly changing. As the object moves along the circle, its velocity and acceleration vectors are constantly changing in magnitude and direction.
