S.I. Unit of Radial Acceleration
Radial acceleration acts along the radius of an object and directed towards its centre. A body in circular motion has two components of acceleration, i.e. radial and tangential directed towards center and tangent of the circle respectively.
Mathematically, it is defined as:
ar = v2/ r
where v is angular velocity and r is angular displacement.
Hence, the unit of radial acceleration ar can be given as:
Unit of ar = (rad/s)2/rad [As SI unit of v and r is rad/s and rad respectively]
On solving we get,
Unit of ar = rad/s2
Radial acceleration is also called normal acceleration. It has same units as that of angular acceleration, i.e. rad/s2.
Unit of Acceleration
Unit of Acceleration is meter per second square or m/s2. Acceleration is the rate at which the velocity of a body changes. The most commonly used units of acceleration are meters per second square (m/s2) and kilometer per hour square (km/h2).
In this article, we will learn the definition of acceleration, the unit of acceleration, units in various systems, sample problems, and frequently asked questions related to the unit of acceleration.
