1.	Kinetic energy of body is E, velocity is doubled then kinetic energy will be
Answer» If velocity is doubled,\xa0Kinetic Energy\xa0increases by 4 times.Kinetic energy of a body is the energy possessed by it, by virtue of its motion, i.e. if the body is moving it will always have kinetic energy.so kinetic energy is directly proportional to v^2coz mass is constantso new kinetic energy changes as (2v)^2 =4v^2so kinetic energy increases 4 times
