5 Energy and Machines
... Energy: the ability to do work There are many different types of energy. This chapter will focus on only mechanical energy, or the energy related to position (potential energy) and motion (kinetic energy). Potential energy: energy of position, or stored energy An object gains gravitational energy, w ...

... Work is done by a section of water applying a force on a second section in front of it over a displacement. According to Newton’s 3rd law, the second section of water applies an equal and opposite force back on the first. Thus is does negative work as the water still moves FORWARD. Pressure*Area is ...
