Chapter 01: Basic Physics for the Respiratory Therapist MULTIPLE CHOICE 1. Power is a measure of which of the following? a. Mechanical energy b. Gravitational potential energy c. The rate at which work is being performed d. The rate at which atoms and molecules move ANS: C Power is a measure of the rate at which work is being performed. The formula P = W/J, where W = watts and 1 watt is equal to 1 J/s, expresses this. Joules are the international standard for expressing energy and work...
