\nIn uniform circular motion, the speed of the object is constant, but its velocity is continuously changing direction as it moves along the circular path. Acceleration is the rate of change of velocity. For an object in uniform circular motion, there is an acceleration directed towards the center of the circle.
\n<\/section>\n
\nThe velocity vector in circular motion is always tangent to the circle at the object’s position. The acceleration, known as centripetal acceleration, is always directed along the radius towards the center of the circle. A line tangent to a circle is always perpendicular to the radius at the point of tangency. Therefore, the direction of acceleration (towards the center) is always perpendicular to the direction of velocity (tangent to the circle).
\n<\/section>\n
\nThe magnitude of the centripetal acceleration is given by a = v\u00b2\/r, where v is the constant speed and r is the radius of the circle. Since there is no component of acceleration along the tangent (tangential acceleration), the magnitude of the velocity (speed) remains constant.
