Key Concepts

Circular Motion

Circular motion refers to the movement of an object along the circumference of a circle. In such motion, the object’s radial distance from the center remains constant, which leads to unique behaviors in the object's acceleration and velocity components.

Centripetal (Radial) Acceleration

Centripetal acceleration is the acceleration directed towards the center of the circular path. It is responsible for continuously changing the direction of the velocity vector, keeping the object in a circular trajectory despite the constant speed.

Radial Velocity

Radial velocity is the component of the velocity vector that is directed along the radius – either towards or away from the circle's center. In uniform circular motion, since the object’s distance from the center does not change, the radial velocity component is zero.

Equilibrium

In mechanics, equilibrium refers to a state where the net force acting on an object is zero, resulting in no acceleration. In circular motion, even if the speed is constant, the presence of centripetal acceleration means there is a net force acting on the object, so it is not in equilibrium.
