Kepler's third law is represented by the following equation:
Find the force of gravitation between two 5.0 kg balls that are 1.5 m apart.
Use G=6.67×10−11 kg2N.m2
7.4×10−10 N
1.1×10−9 N
Calculate the gravitational force between two objects when they are 0.750m apart. Each object has a mass of 5.00kg.
2.96x10-9N
3.00x10-6N
2.22x10-9N
2.23x10-8N
If the mass of either m1 or m2 is increased then the force of gravitation between them will...
increase
decrease
stay the same
Kepler's First Law states
objects attract other objects with a force that is directly proportional to the product of their masses
the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun
An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.
Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.
