How a ballet dancer spins rapidly at one place?
B allet dance, one of the most entertaining form of dance that we like to watch. If you had ever watched ballet , you must had watched the performer to rotate rapidly at one place. But have you ever thought how she do that easily. What is the technique behind this, that a normal person don't know and fails to perform this act.So let's explore this topic today. But before that we have to be clear about some basic concepts of motion of a body. So let's begin that first step by step:- 1.Momentum as you all know is the product of the mass of an object and it's velocity. This definition of momentum is limited to the linear motion of the object. But when the object is rotating about an axis, it is undergoing rotational motion. It should be clear that rotational analogue of momentum is called angular momentum. We should now learn about the conservation of momentum which states that:- "Momentum neither be created nor be destroyed". So from the above
