Work done in the motion of a body over a closed loop is zero for every force in nature.
Options
True
False
Advertisements
Solution
This statement is False.
Explanation:
The work done during the motion of a body over a closed loop is zero exclusively when influenced by a conservative force such as gravity or electrostatic forces. When the forces are non-conservative, like friction, the work done is not zero. Specifically, the work done by friction over a closed loop does not equal zero.
