Question

what is meant by , "work energy theorem is an integral form of newton 's second law. it involves an integral over an interval of time. in this sense the temporal information contained in the statement of Newton 's second law is integrated over and isn't available explicitly "

Answer 1

• In the case of variable force, the work energy theorem is expressed in the form of integration over time and not available explicitly.
• But, in the case of constant force, the work energy theorem is not expressed in the form of integration and it can be available explicitly.
