A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
Physical laws play an important role in Science and are considered fundamental. Many laws of physics are built after several researches or some are a modification of existing laws and theoretical research. This article deals with important laws of physics which will help in the understanding of various concepts.
