5.4.1: Introduction
-
Work is the energy associated with the action of a force.
-
-
5.4.2: Work Done by a Constant Force
-
The work done by a constant force is proportional to the force applied times the displacement of the object.
-
-
5.4.3: Work Done by a Variable Force
-
Integration is used to calculate the work done by a variable force.
-
-
5.4.4: Work-Energy Theorem
-
The work-energy theorem states that the work done by all forces acting on a particle equals the change in the particle’s kinetic energy.
-
-
5.4.5: Potential Energy and Conservation of Energy
-
Conservative force—a force with the property that the work done in moving a particle between two points is independent of the path it takes.
-
-
5.4.6: Power
-
In physics, power is the rate of doing work—the amount of energy consumed per unit time.
-
-
5.4.7: CASE STUDY- World Energy Use
-
The most prominent sources of energy used in the world are non-renewable (i.e., unsustainable).
-
-
5.4.8: Further Topics
-
Thermal, chemical, electric, radiant, nuclear, magnetic, elastic, sound, mechanical, luminous, and mass are forms that energy can exist in.
