Um pêndulo é constituído de uma esfera de massa 2,0 kg, presa a um fio de massa desprezível e comprimento 2,0 m, que pende do teto.
O pêndulo oscila, formando um ângulo máximo de 60° com a vertical. Nessas condições, o trabalho realizado pela força de tração que o fio exerce sobre a esfera, entre a posição mais baixa e a mais alta, em joules, vale:
