Teaching unit about the gravitational field for 2nd high school. Historical background. The gravitational force. The field strength. Energy in the gravitational field. Some consequences of the theory.
PRIOR KNOWLEDGE: Basic mechanical issues: equations of motion (and mrua mru), Newton's laws. Conservation of mechanical energy
METHODOLOGY: Behavioral
LEARNING OBJECTIVESTo understand the process that led to the establishment of the law of universal gravitation and its relation with Kepler's empirical laws. To explain the importance of the law of gravitation in the study of the movement of astronomical objects in the solar system, artificial satellites and tides. To learn the concepts of field intensity and gravitational potential energy. To understand how phenomena like Earth's rotation may change our perception of gravity. To be able, in simple cases, to carry out predictions about the values of field intensity, orbital data for satellites and energy in gravitational phenomena.
