In this live lecture i'll discuss Previous years question Horizontal circular motion And Banking Of Roads. circular motion is a movement of an object along the circumference of a circle or rotation along a circular arc. It can be uniform, with a constant rate of rotation and constant tangential speed, or non-uniform with a changing rate of rotation. Horizontal circular motion is defined as a motion that takes place on a horizontal surface that is circularly orientated. It refers to the motion when the body is moving on a horizontal surface and circular path. This was also differentiated from vertical circular motion. Banking of roads is defined as the phenomenon in which the outer edges are raised for the curved roads above the inner edge to provide the necessary centripetal force to the vehicles so that they take a safe turn.
