1.	A girl is swinging on a swing in the sitting position. How will the period of swing be affected if she stands up?
Answer» Solution : This can be explained using the concept of a simple pendulum. We know that the time period of a simple pendulum is given by ` T = 2PI sqrt(l/g) i.e., T PROP sqrtl` When the girl stands up, the distance between the POINT of suspension and the centre of mass of the swinging BODY decreases i.e., I decreases, so I will also decrease.
