Work Energy And Power Physics Grade 12

Concepts of work kinetic energy and potential energy are discussed.

Work energy and power physics grade 12.

3 when a physicist is talking about work he mainly talks about a force causing a displacement of an object in the same action of line. Determine the work done on the car. It explains how to calculate the average power exerted by a constant. In this live grade 12 physical sciences show we take a close look at work energy power.

They are probably the first thing you learn in your physics class. In this lesson we revise the definition of work as well as revise the idea that power is the rate of transfer of energy. Work energy and power. Grade 10 physical sciences.

Work power and energy 2 work if an object or system such as your body exerts a force on an object and that force causes the object s position to change you are doing work on the object. Revision of grade 9. Physicists mean something very specific when they talk about work. Work energy and power are the most used terms in physics.

Work and energy can be considered as two sides of the same coin. We learn that power can be calculated using the force average velocity of an object. In physics we use the term work to describe the process of transferring energy from. States of matter and the kinetic molecular theory.

We talk about going to work doing homework working in class. They apply a cumulative force of 1080 n to push the car 218 m to the nearest fuel station. These concepts are combined with the work energy theorem to provide a convenient means of analyzing an object or system of objects moving between an initial and final state.
