1. The problem statement, all variables and given/known data Is the following statement true or false: "Energy is expended when a person exerts a force on an object." 2. Relevant equations 1) From the equation Work Done = Force x Distance, if a force is exerted, but no distance moved, then no work is done. Hence, the statement is false? 2) However, when a person exerts a force, is he not expending chemical potential energy? In other words, there is an energy change from chemical to thermal. Hence, the statement is true? 3. The attempt at a solution I am not sure which of the above is right. Will appreciate any help. Thank you!
