Newton’s Law of Gravitation - NASA

1 newton s Law of GravitationDuration: 1-2 class periodsEssential Questions: How do the acceleration and force due to gravity depend on the radius and mass of a planet? How does the mass of a falling body affect the rate at which it falls in a gravita-tional field?Objectives: Students see that the acceleration of an object due to gravity is independent of its mass. determine what they would weigh on other planets. see that the force they feel from gravity depends on the radius and the mass of the Concepts: newton s Law of Gravita-tio n states that two objects with masses m1 and m2, with a distance r between their cen-ters, attract each other with a force F given by: F = Gm1m2/r2where G is the Universal grav -itational Constant (equal to: x 10-11Nm2/kg2).

Newton: Isaac Newton was the person who realized that all massive objects in the Universe apply the force of grav-ity to all other massive objects. An apple didn’t really fall on his head, but he did realize that the force causing an apple to fall is the same as the force causing the Moon to orbit the Earth – the Earth’s gravity. Girl ...
