Weight In this lesson weight is defined and calculated and the idea of weightlessness is investigated. In symbols the magnitude of the attractive force F is equal to G the gravitational constant a number the size of which depends on the system of units used and which is a.

Law of Universal Gravitation Problems 1.
Mathematically this law and the magnitude of the force due to the gravitational interaction between two particles is expressed with 1F grav Gmm 2 r2 51 where G6671011 Nm2kg2 is the universal gravitational constant m 1 and m 2 the particles masses and r the distance between them. According to the universal law of gravitation the force between two objects is dir ectly pr oportional to the pr oduct of their masses. Newtons Law of Universal Gravitation is a law of physics which states that objects attract each other due to their mass. Law of Universal Gravitation Problems 1.
