The Mechanical Energy Variation Theorem and the Vertical Movement
In this lesson moment, students will find out what kind of movement does a ball perform, when let loose from a height h and depending to the contact surface. But, in order to do so, they have to choose the ball's mass and the height from which the ball is let loose.

Mechanical Energy Preservation Law: An object's Movement on an Inclined Surface
In this interactive moment, students are asked to fill the pantry with winter supplies, by helping Chris to carry the supplies to the pantry as fast as possible. They have to choose the hollow into which Chris must carry the nuts using the buttons on the lower right side.

Mechanical Energy Preservation Law: An Object's Movement on the Vertical
In this educational moment, students can learn that the mechanical energy of an object on which elastic and gravitation forces do act, is preserved.

Potential Elastic Energy: Experiment
In this interactive moment, students can learn that during the spring's loosening, the spires' position to one another will modify and the mechanical energy of the compressed resort is a potential energy of elastic type.

Potential Elastic Energy: Introduction
In this interactive game, students are trying to hit the moving apple, using the bow and the arrows. In order to do that, they have to click on the bow and move the pointer up and down to orientate the arrow's direction; then let the mouse button go, in order to launch the arrow towards the apple.

Potential Gravitational Energy: Experiment
In this interactive experiment, students can observe that for each mechanical state of a physical system, characterized by a certain relative position of its components (which interact), there is a corresponding potential energy.

Mechanical Work of a Constant Force
In order to answer some questions, students are asked to pull the cart three times in a row, one time for each position in which the string can be attached to it. To tie the string to the cart, they have to fix the force F in red, in the desired position.
