Question

give an example in which a force does work on a body but fails to change its kinetic energy

Answer 1

Explanation:

give an example in which a force does work on a body but fails to change its kinetic energy

>>if you take a small steel ball and drop it in a thick syrup, you would see that the ball descends with a uniform speed (terminal speed). In this case, gravity is doing positive work, and the syrup does a negative work.

Answer 2

$\huge\boxed{\texttt{\fcolorbox{Example :- }}}$

When a body is ppulled over a rough horizontal surface with a uniform velocity. Work is done ono the body by the applied force, but its KE remains unchanges.
