Newton's Universal Law of Gravitation
What is the value of the universal gravitational constant G?
6.67 x 10^-11
Give an example of a third law pair involving gravity.
Earth on Moon, Moon on Earth.
What is Newton's law of Universal Gravitation? Describe this law in words, then write this law as an equation.
F= force G = gravity M= larger mass m = smaller mass r= distance The Universal Laws of Gravitation is the pull of gravity between two objects.
Two 1 kg masses are 1 m apart, what is the gravitational force between them? (Show your work)
The gravitational force between the two objects is F = (G)(1)(1)/ (1) = G
What is the gravitational force between the Earth and a 1 kg object (Show your work)
What is the gravitational force between the Earth and a 1 kg object (Show your work)
Two objects with mass m1 and m2, are located a distance d apart. What happens to the size of the gravitational force between these two objects if you doubled m1? What would happen to the acceleration of mass m1? Of mass m2?
☯If the m1 doubles. the gravitational force doubles. ☯ m1 acceleration would double if the mass doubled. ☯ m2 acceleration would stay the same if the mass stayed the same.
