Answer 2

Dear Student,

◆ Answers -

(i) The total of kinetic energy and potential energy of molecules of a

system is called its mechanical energy.

(ii) Work done = – W indicates that work is done on the system.

● Extra information -

• Mechanical energy is of two types - kinetic (energy of motion) and potential (stored energy).
• When work is done by thr system, it is positive and when work is done on the system, it is negative.

Thanks dear. Hope this helps you...
