Archimedes' principle is a principle of physics that states that a body wholly or partially submerged in a static fluid, will be pushed with a vertical upward force equal to the weight of the volume o ...
The educational resource shows a visual about the apparent gravity: the gravitational field intensity, g, is not the same everywhere on the surface of the earth. If the period of the rotation were dif ...
The educational resource shows a visual about the measurement of g: a simple pendulum is sufficient to measure the intensity of the gravitational field g. Before beginning the experiment, invent some ...
Concept of attraction among masses
Concept that gravity is caused by the matter
The educational resource shows a visual about the difference between mass and weight: mass is not the same as weight, although in ordinary life both words are used with the same meaning. In Physics, m ...
Concept of pressure and depth
The educational resource shows a visual about tides: the effect of the gravitational force of the moon and the sun on the earth can be seen in the tides.
The educational resource shows a visual about the measurement of G: in 1798, Henry Cavendish, used an ingenious method to measure G, the constant of Universal Gravitation. He used a torsion balance, a ...
