Circular Motion and Gravitation
Which of Newton’s laws explains why a planet orbits the sun?
If a planetary object were found with twice the radius and eight times the mass of Earth, how would the acceleration due to gravity at its surface compare to that on Earth?
Two planets have identical masses but different radii; if Planet X has half the radius compared to Planet Y, how does gravity compare between their surfaces?
The orbital speed of Uranus is ______ the orbital speed of Earth.
If Planet X has twice the mass of Earth but the same radius, what would be the acceleration due to gravity on the surface of Planet X compared to that of Earth?
If the gravitational acceleration due to gravity at the surface of planet Y is half that of Earth, how much larger must planet Y's radius be compared to Earth's assuming they have the same density?
Units of gravitational field are
