WebIndicate True or False about the Work Kinetic-energy theorem? If positive work is done to an object, its speed must increase: T or F. The theorem establishes a general relation between the kinetic energy of an object and the work done to it by external forces: T or F. If negative work is done to an object, its kinetic energy must decrease: T or F. WebKinetic energy is the form of mechanical energy which depends upon the position of an object. If an object is at rest, then it does not have any kinetic energy. If an object is on the ground, then it does not have any kinetic energy. Question 8 30 seconds Q.
