In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. In other words, a force is that which can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or which can cause a flexible object to deform. Force can also be described by intuitive concepts such as a push or pull. A force has both magnitude and direction, making it a vector quantity. Newton's second law, F = ma, was originally formulated in slightly different, but equivalent terms: the original version states that the net force acting upon an object is equal to the rate at which its momentum changes.
Related concepts to force include: thrust, which increases the velocity of an object; drag, which decreases the velocity of an object; and torque which produces changes in rotational speed of an object. Forces which do not act uniformly on all parts of a body will also cause mechanical stresses, a technical term for influences which cause deformation of matter. While mechanical stress can remain embedded in a solid object, gradually deforming it, mechanical stress in a fluid determines changes in its pressure and volume.
Mohan Babu (born Manchu Bakthavatsalam Naidu) is an actor and producer in Telugu Cinema. He is also an educationist and a former Member of Parliament – Rajya Sabha from Andhra Pradesh. He received the Padma Shri in 2007.
Mohan was born on 19 March 1952 at Modhugulapalem village near the banks of the river Swarnamukhi, and sandwiched between two famous pilgrim centers, Tirupati (abode of Lord Venkateshwara) and Srikalahasti (abode of Lord Vayulingeswara) in Chittoor district of Andhra Pradesh. He has three younger brothers – Ranganath Chowdary, Ramachandra Chowdary and Krishna – and a sister Vijaya. He had his schooling at Yerpedu village and Tirupati. He took his degree in Physical Education in Chennai. He worked as a physical education instructor for a brief while, before making his debut as an actor in the Telugu film industry. Mohan Babu also worked in the film direction department for about half a decade in the early 1970s. He was a class mate of Rajinikanth while they studied at the Madras Film Institute.
