In this 17-lesson series, we'll look at Energy, Work, Kinetic Energy, Power, Potential Energy and the Conservation of energy.

We'll start by looking at how to find the amount of work done by a constant force acting in either one and two dimensions. Then, we'll look at how this changes when we're dealing with a variable force instead of a constant one. Last, we'll dig into work done by springs.

Next, we'll turn our attention to look at work, kinetic energy, the work-kinetic energy theorem and power as well as problems involving each of these. The relationship between work and the change in kinetic energy is described by the Work-Kinetic Energy Theorem, which we'll derive in general terms from the definition of work, Newton's Second Law, and the third equation of kinematics. The work-kinetic energy theorem is a tremendously useful tool for solving problems involving work and forces, and we'll show you how it can be used and applied in several different physics problems.

Then, we'll focus on potential energy. As part of this, we'll look at the relationship between work and gravitational potential energy, the difference between conservative and non-conservative forces, and the calculation of potential energy.

Last, we'll look at Conservation of Energy and problems involving this concept. We'll also cover potential energy functions, energy diagrams, and work with non-conservative forces.

This lesson was selected from a broader, comprehensive course, Physics I. This course and others are available from Thinkwell, Inc. The full course can be found at The full course covers kinematics, dynamics, energy, momentum, the physics of extended objects, gravity, fluids, relativity, oscillatory motion, waves, and more. The course features two renowned professors: Steven Pollock, an associate professor of Physics at the University of Colorado at Boulder and Ephraim Fischbach, a professor of physics at Purdue University.
