On which celestial object (outer space) would your mass be the greatest?
Earth
Jupiter
Sun
Your mass doesn't change on different celestial objects
What is the proper setup of the gravitational force formula?
Fg= Gm2/r
F=ma
Fg= Gr2/(m1+m2)
Fg= G (m1m2)/r2
Calculate the gravitational force between a 15-kg chinchilla and a 65-kg dog which are separated by 0.30 m.
Fg = 3.7*10-8 N
Fg = 1.3*1012 N
Fg = 1.1*105 N
Fg = 7.2*10-7 N
What would the gravitational force be between the Sun and Mars if they were 2.3*1011 m apart? The masses for the Sun and Jupiter are 1.99*1030 kg and 6.42*1023kg, respectively.
Fg = 3.8*1015 N
Fg = 2.8*10-42 N
Fg = 1.6*1021 N
Fg = 4.6*10-75 N
What does the variable G in the gravitational force equation represent? Fg = G r2m1 m2

True or False: The gravitational force each tennis ball acts on the other is the same.
True
False
When calculating the r value for gravitational force, where do we measure between two objects?
The sum of their diameters
The center of their masses
The furthest reaches of their orbits
The tips of one of their poles
Calculate the gravitational force between two objects when they are 0.750m apart. Each object has a mass of 5.00kg.
2.96x10-7N
3.00x10-9N

A 500 kg asteroid is located 3.4 x107m from the center of Earth. The mass of Earth is 6.0x1024 kg. What is the gravitational force between the asteroid and Earth?
F = GMm/r2
G= 6.67 x 10-11
1.73 x 102 N
4.63 x 105 N
2.94 x 103 N
6.42 x 104 N
The number 6.67 x 10 -11 N* m2 / kg2 is called the
Universal speed constant
centripetal force
Universal Gravitational constant
Earth's Gravitational constant
