Answer:
The term “Uniform circular motion” is the kind of motion of an object in a circle at a constant speed. With uniform circular motion, as an object moves in a particular circle,
Angular Velocity (ῶ) = Δθ/Δt
Angular Velocity is a vector quantity. Its unit is rad/s. The relation between the linear velocity (v) and angular velocity (ῶ) is
v = rῶ
Centripetal Acceleration
It refers to an acceleration that acts on the body in circular motion whose direction is always towards the center of the path.
Centripetal Acceleration (α) = v2/r = rῶ2.
The magnitude of this acceleration by comparing ratios of velocity and position around the circle. Since the particle is traveling in a circular path, the ratio of the change in velocity to velocity will be the same as the ratio of the change in position to position. It is also known as radial acceleration as it acts along the radius of the circle. Centripetal Acceleration is a vector quantity and the unit is in m/s2.
