Using a roller coaster as an example, the transformation of mechanical energy from the form of potential to the form of kinetic and vice versa is explained and illustrated in the animation.

The intricate relationship between work and mechanical energy is depicted in the animation for students to be able to visualize.

Consider an ordinary dart projected from a toy dart gun and moving through the air. Students analyze work and energy of the motion of the dart with this animation.

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated...

The motion of a pendulum is a classic example of mechanical energy conservation. See the mechanics at work here in this animation.

In this tutorial the concept of how electrical energy is transformed is introduced. Learn how electric charges actually work and take the interactive quiz to assess your understanding.
