: We know that the rate of asymmetric growth over time is called acceleration. Acceleration is generally of two types - 1. Smooth acceleration , 2. Uneven acceleration. Again, if the velocity of an object does not increase at the same rate in a certain direction, that is, if it is not even, then it is called unequal acceleration. The acceleration of an object falling under the influence of gravity is a balanced acceleration because it increases at a rate of 9.8 m / s- 1 per second towards the earth's surface. But the acceleration of an object in a circular or akabaka path does not increase at the same rate in a certain direction but the acceleration of an object in an akabaka or circular path increases or decreases at different rates in different directions. So the acceleration of an object in a circular or Akbaka path cannot be a balanced acceleration. Since the velocity of an object in a circular or akabaka path does not increase at the same rate i.e. the rate of increase of velocity is not equal, the acceleration of an object in a circular or akabaka path is called unequal acceleration. Cars , bicycles , rickshaws go on the Akabaka road so their acceleration is uneven acceleration. Thank you!
