- 6.1: Introduction
- Work is the energy associated with the action of a force.
- 6.2: 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.
- 6.3: Work Done by a Variable Force
- Integration is used to calculate the work done by a variable force.
- 6.4: 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.
- 6.5: 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.
- 6.6: Power
- In physics, power is the rate of doing work—the amount of energy consumed per unit time.
- 6.7: CASE STUDY: World Energy Use
- The most prominent sources of energy used in the world are non-renewable (i.e., unsustainable).
- 6.8: Further Topics
- Thermal, chemical, electric, radiant, nuclear, magnetic, elastic, sound, mechanical, luminous, and mass are forms that energy can exist in.
