= 60 kg; m
2
= 60 kg; d = 1 m
2.4 x 10-5 N
0 N

4
In the equation
F
grav
= G * m
1
* m
2
/ d
2
the symbol
G
represents...
the acceleration of gravity
the gravitational constant
gravity
5
The value of G is a huge number; that's why the attraction between the Sun and Earth is so big
True
False
6
The greater Earth's radius is, the _______ that another object will be attracted to it.
less
more
7

8
Astronauts in the space shuttle seem to float around because...
there's no weight in space
there is no gravity in space
there is no air resistance
the astronauts are in continuous free fall
9
What's so
universal
about Newton's law of gravitation?
the accelerat. caused by gravity is the same for all objects
all objects with color attract
the force of gravity acts between all objects, even 2 people
the amount of grav. force is the same for all objects
10
What's the F
grav
on a student on planet Z : m

12
The idea that any 2 objects gravitationally attract each other is a theory with no evidence
true
false
13
The more massive the Earth is, the _____ that another object will be attracted to it.
more
less
14
The force of gravity between a planet and an object on its surface depends upon...
all of these
the mass of the planet
the mass of the object
the radius of the planet
15
Newton proposed the law of universal gravitation because he had been studying...
the motion of the moon and other space objects
actually Newton had no evidence and just made a lucky theory
the gravitational interaction between small objects on Earth
the fall of an apple to the Earth
