PPT-Review What is potential energy?

What is kinetic energy Give an example of each Forms of Energy Forms of Energy 1 All energy falls into two categories Potential stored energy and energy of position Kinetic motion of . David Like. Overview of the problem. Refresher of useful equations. Problem. Questions. Outline. To estimate the energy involved in a shockwave similar to that which I reported on, consider a 2D square . 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).. Space travel problems. Escape speed. Orbital . energy. Multiple objects. Lecture 14: Gravitational potential energy and space travel. Gravitational potential energy. , attractive.  . Conservative force. Gravitational (U=. mgh. ) . Elastic (U=1/2kx. 2. ). Sometimes it is more helpful when you have potential energy as a function of Position to find Potential energy first and derive the force from there.. Chapter 8.

QOD: What is the difference between potential and kinetic energy? . 1. . energy. – the ability to do work. energy is transferred by a force moving an object through a distance. when work is done on an object, energy is transferred to that object . Law of Conservation of Energy. aka. First Law of Thermodynamics. the . first law of thermodynamics.  is a version of the . law of conservation of energy. , adapted for . thermodynamic.  systems. The . It takes . work. to lift a mass against the pull (force) of gravity. The force of gravity is . m. ·. g. , where . m. is the mass, and . g. is the gravitational . acceleration. F . = mg. (note similarity to . POTENTIAL. ELASTIC. CHEMICAL. GRAVITATIONAL. FORMULA.  . Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a . doubling. of the height will result in a . Tuesday May 21 Overview Energy Motion Object Potential Mechanical Energy Chemical Elastic Chemical Gravitational Elastic Gravitational The nature of energy Energy of a spinning bicycle wheel Energy stored in food . Electric Potential (Energy). Charges. The fundamental rule at the base of all electrical phenomena is that . like charges repel and opposite charges attract. An object that has unequal numbers of electrons and protons is . LO:. . We will understand that energy can take many forms but the total energy in a system is constant.. . CT: . I . will investigate and calculate the changes of different forms of energy.. . The Law . 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. Learning Objectives. I can mathematically rearrange the potential energy equation.. I can calculate Potential Energy using the formula.. Gravitational Potential Energy (GPE). Potential Energy that depends upon an objects height above a reference point.
