Subliniază răspunsul corect: În acelaşi timp un corp se poate / nu se poate afla în mai multe tipuri de echilibru. O minge va tinde să ocupe poziţii cât mai joase / înalte pe o suprafaţă de sprijin. La o curbă spre stânga şoselele sunt înclinate astfel încât, când plouă, apa se scurge spre exteriorul / interiorul curbei. Acrobaţii folosesc o bară lungă şi subţire (un balansier) / un toiag pentru a-şi menţine echilibrul când merg pe sârmă.
