Answer 1

When body moves around a circular track two kinds of accelaration arises one is tangential and another is centripetal .

when body moves round a cicular track , the accelaration that is pointed towards centre is called centripetal accelaration .

Now , if body is moving in a straight line with constant speed , then its accelaration is zero

If body is moving in circular track with constant speed is accelaration is not zero because accltn is vector quantity , its magnitude though remains same due to uniform speed but its direction always changes .
