By the end of this section, you will be able to define conservative force, potential energy, and mechanical energy; explain the potential energy of a spring in terms of its compression when Hooke's law applies; and use the work-energy...

By the end of this section, you will be able to define nonconservative forces and explain how they affect mechanical energy, and to show how the principle of conservation of energy can be applied by treating the conservative forces in...

By the end of this section, you will be able to explain work as a transfer of energy and net work as the work done by the net force and to explain and apply the work-energy theorem.

This site from Georgia State University Physics Department defines and explains the concept of potential energy. Using equations and graphics to illustrate the idea, it discusses the many types of potential energy (gravitational,...

By the end of this section, you will be able to explain gravitational potential energy in terms of work done against gravity, show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh,...

The Illinois Institute of Technology provides this site. The site contains a graphing activity which illustrates that a constant force exerted upon an object results in constant acceleration. Rolling carts and stopwatches are used to...

Students work in teams to investigate how aerospace engineering relates to sports, especially golf ball design and the physics of bounce. They use this information to determine whether these aerospace principles can be applied to...
