The equation for Newton's Law of Universal Gravitation is:
Fg = (Gm1m2)/d2
Fg = the gravitational force between the two masses, measured in Newtons
G = 6.67 E -11 N*m2/kg2 (first measured by Henry Cavendish)
m1 = the mass of the first object, measured in kilograms
m2 = the mass of the second object, measured in kilograms
d2 = the distance between the objects squared, measured in meters
Here is a sample problem: The earth and the sun are 1.5 E 11 meters apart. Use Newton's Law of Universal Gravitation to calculate the force of gravity between the earth (mass = 6.0 E 24 kg) and the sun (mass = 2.0 E 30 kg).
My teachers work:
Fg = (Gm1m2)/d2
Fg = [(6.67 E -11 N*m2/kg2 )(6.0 E 24 kg)(2.0 E 30 kg)]/(1.5 E 11 m)2
AND her answer ended up being: Fg = 3.6 E 22 N
I have NO CLUE how she got that answer! Whenever I try to work it I never get the same thing as her. HELP!!!!
