Explanation:

hope this will help u...

Answer 2

Answer:

According to work energy theorem the work done by the force is equal to increase in the kinetic energy of the body. If the kinetic energy of the body increases then work is positive and if the kinetic energy decreases work is negative. Work done by conservative forces to move a particle in closed path is zero.
