how can we calculate the work that a child has to make to move towards
the center of a merry-go-round?(a work coming from an internal force)

i already know that we can find it by the difference between

K (final) - K (initial) using the Work-Energy Theorem, but i d like to know how
else we can calulate this work.

e.g dW=τdθ

thank u very much
