Concept of density

The educational resource shows information about the kinetic energy: the kinetic energy of an object is its capacity to change its environment, because it is moving. How far will two balls with different masses and velocities penetrate a block of snow?

Concept for measuring the forces. Dynamometer

Concept of density. Performing calculations.

These activities are designed to be viewed on a 17-inch screen and with a resolution of 1024 x 768 pixels because some windows show measurements in centimetres and millimetres that, when viewed with another configuration, won't correspond with reality; and the size of some windows can even be too big. This unit only deals with a basic knowledge on length, volume and weight units, as studied in primary school. It does not deal with the other units of the International System. Moreover, the stu...
