physics f4 - chap 3.1 Newton’s Universal Law of Gravitation

3.1.1 Explain Newton’s Universal Law of Gravitation: F =G m1m2/r^2 3.1.2 Solve problems involving Newton’s Universal Law of Gravitation for: (i) two static objects on the Earth (ii) objects on the Earth’s surface (iii) Earth and satelites (iv) Earth and Sun 3.1.3 Relate gravitational acceleration, g on the surface of the Earth with the universal gravitational constant, G 3.1.4 Justify the importance of knowing the values of gravitational acceleration of the planets in the Solar System. 3.1.5 Describe the centripetal force in the motion of satellites and planets system. Centripetal Force, F = mv^2 /r 3.1.6 Determine the mass of the Earth and the Sun using Newton’s universal law of gravitation and centripetal force.
