Energy Skate Park: Basics

Learn about conservation of energy with a skater gal! Explore different tracks and view the kinetic energy, potential energy and friction as she moves. Build your own tracks, ramps, and jumps for the ...

Energy Forms and Changes

Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy. See how energy is transferred between objects. Build your own system, with energy sources, changers, and users ...

Gravitatonial potential energy

The educational resource shows a visual about gravitational potential energy: the calculation of gravitational potential energy is very easy for small heights, as it is given by the formula Ep=mgh, wh ...

The changing Earth

The educational resource shows a Flash animation about the greenhouse effect The Earth is an open material system, because it interchanges matter and energy with outer space.

The first law of thermodynamics

The educational resource shows an interactive animation about the first law of thermodynamics:when we heat a pressure cooker, the heat we supply to the water is used to increase the temperature of the ...

The second law of thermodynamics

The educational resource shows an interactive animation about the second law of thermodynamics for heat engines: it is not possible to achieve perpetual motion based on continuous reciprocal conversio ...

Work of friction

The forces of friction, which oppose displacement, also carry out work when a body is moving. The work of friction is converted into heat. The greater the force of friction, the more force must be exe ...

Thermal energy

The educational resource shows information about the concept of thermal energy: thermal energy is due to the movement of the particles which make up matter. The particles of a body at a low temperatur ...

Conservation of energy (II)

The principle of conservation of energy states that energy is neither created nor destroyed; it is just transformed from some types of energy into others. The following visual will help you to underst ...

Graph representing work

The area of the graph between the curve F and the X axis, represents the work carried out by the force between the two positions x0 and x. Review how to use the following visual and carry out the two ...
