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.
