To estimate the energy involved in a shockwave similar to that which I reported on, consider a 2D square . Osmosis & Plant cells. Plants & water potential. Plants can use the potential energy in water to perform work.. Tomato plant regains turgor pressure – cell pushes against wall due to uptake of water. 6.5 Nerves, Hormones, and Homeostasis. How do neurons communicate and relay information?. http://www.pennmedicine.org/encyclopedia/em_DisplayAnimation.aspx?gcid=000089&ptid=17. Action Potential. ~1900 Julius Berstein suggested that nerve impulses were an electrochemical message created by the movement of ions through the nerve cell membrane.. Two Types of Energy. Energy. Energy . is often defined as the ability . to change matter or to . do work. Work Occurs when a force is applied to an object and the object moves a distance. Work is measured in a unit called joules (J).. Introduction. Zeta potential is the charge that is located at the slipping point of a particle in a medium.. Zeta . potential . is used . mostly in Colloidal chemistry. .. If the magnitude of zeta potential is > 30mV then it is in stable suspension. بسم الله الرحمن الرحيم. Objectives .

Use the Nernst equation to calculate the values of Nernst potential for Na, K & Cl. Click on the link and watch this brief interview . by the book’s author. Then reflect through the slides recalling the main ideas. Who?. Potential:. Competence: . Competence com·pe·tence. ˈkämpətəns/. Potential Energy. Definition: The stored energy resulting from the relative positions of objects in a system. Potential energy is measured in Joules . 1 joule = 1 kg•m²/s². Ex. An apple is hanging from the branch of a tree. The energy that could potentially do work on the apple results from its position above the ground. n . Naval Training System. Lt Cdr . Habib. 2.

Energy associated with forces that depend on the position or configuration of a body. Objects acquire potential energy when work is done on it. As an object loses potential energy, it can do work. Potential energy is the capacity to do work even if not doing work yet.
