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: 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.

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.

Inclined Plane Slope

In this moment, students can change the parameters and notice the effects and the elements of a simple mechanism, the inclined plane slope.

Application to Pascal’s Law – Drum Break

In this interactive moment, students can notice the drum brake, as an application of Pascal's law.
