Explore the basic force that rules the Nature, i.e., gravitation and expand its importance in everyday science. Clearly observe and reflect on the Kepler s laws of planetary motion. State and relate the Newton s universal law of gravitation to everyday science. Observe and reflect on the variation of acceleration due to gravity at different places of Earth. Distinguish between mass and weight of the object. Discover the concept of weightlessness and apply it to everyday science. Explore about the ocean tides and extend it to different types of tides. Explore and discuss about gravitational potential energy. Investigate, explore and formulate Kepler s laws of planetary motion. Develop and formulate orbital velocity, escape velocity and energy of artificial satellites.
