The Basic Energy Model1. The Basic Energy Model ( Intro )a. The cardinal signifiers of energy are kinetic. possible. and thermic energy. B. Most of the clip will be spent understanding the transforming of energy. c. Energy can be transformed by using a mechanical force. d. The jurisprudence of preservation of energy. energy is neither created nor destroyed. is consider by scientists to be the most of import jurisprudence of nature. 2. Systems and Energy
a. Every system has a entire energy which is the amount of all energies involved in the system. B. A system can hold multiple types of energy that need to all be included in the entire energy. 3. Energy Transformations
a. Energy of one sort can be transformed into another sort of energy to salvage everyone from holding a dull life. B. It is easier to change over kinetic. possible. and chemical energy into thermic energy. but it is harder to alter it from thermic back to one of the other three. 4. Energy Transfers and Work
a. An exchange of energy between system and environment is called an energy transportation. B. The two primary procedures of energy transportation are work. which is the mechanical transportation of energy. or heat. which is the nonmechanical transportation of energy caused by differences in temperature between system and environment. c. The basic energy theoretical account shows how energy transportations in and out of a system and besides energy transmutations within the system. d. In natural philosophies. work is the procedure of reassigning energy from system to energy or frailty versa. e. Energy is transferred as work merely when the system moves while the force acts otherwise there is no work being done. 5. The Law of Conservation of Energy
a. Work done on a system changes the system’s energy by precisely the sum Force of work that was done. B. An stray system is a system that has no environment moving on it doing at that place to be no transportation of energy lone transmutations of energy. c. The entire energy of an stray system is conserved.
II. 10. 2Work1. Work ( Intro )a. Lone external forces can alter the entire energy of a system. B. The larger the supplanting. the greater the work done. c. The stronger the force. the greater the work done.d. The J is the unit for all signifiers of energy.e. Work is a scalar measure.2. Force at an Angle to the Supplantinga. A force does the greatest sum of work while moving in the same way as the supplanting. B. The mark ( positive or negative ) of W is determined wholly by the angle Theta between the force and the supplanting. c. The entire work is the amount of work done by each force. d. The entire work is besides the entire energy transportation to the system from the environment or from the system to the environment. 3. Forces That Do Not Work
a. Force on an object doesn’t ever do work.B. If the object undergoes no supplanting while the force Acts of the Apostless. no work is done. c. A force perpendicular to the supplanting does no work. d. If the portion of the object on which the force acts undergoes no supplanting. no work is done.
