Law of Universal Gravitation

Universal Gravitation gravity is a force of attraction between any two masses gravity is a UNIVERSAL force –universal meaning of, affecting, or done by all things in the world.

Newton’s Law of Universal Gravitation Force between two objects: F = G m1m2m1m2 d2d2 m 1, m 2 : masses of the objects d: distance between objects’ centers of mass G: universal gravitational constant, 6.67  10 –11 Nm 2 /kg 2

Universal Gravitational Constant G = 6.67x Nm 2 /kg 2 The constant is derived from the force that occurs between two 1 kg masses 1 m apart

2 Things to Know about UG: 1.As MASS increases, the FORCE increases *** If the top of a fraction gets bigger, the whole answer gets bigger as well.

2.As DISTANCE increases, the FORCE decreases *** If the number on the bottom part of the fraction gets bigger, then the whole answer will get smaller.

Practice Problem Tom has a mass of 70.0 kg and Sally has a mass of 50.0 kg. Tom and Sally are standing 20m apart on the dance floor. Sally looks up and sees Tom. She feels an attraction. Find the force of gravitational between Tom and Sally.

Practice Problem What is the gravitational attraction between two spheres (m = 1.67 X kg) at a distance of 5.0 X m?

Practice Problem A 1 kg mass weighs 9.8 N on Earth’s surface, and the radius of Earth is roughly 6.4 x 10 6 meters. Calculate the mass of Earth.
