Lesson: Gravitational Forces near Planetary BodiesPhysics
In this lesson, we will learn how to calculate the acceleration due to gravity for planetary bodies near the surface of such planetary bodies.
Sample Question Videos
Find the acceleration due to gravity on the surface of Mars. Use a value of kg for the mass of Mars and a value of m for its radius.
The acceleration due to gravity on the surface of a planet is three times as large as it is on the surface of Earth. The density of the planet is known to be twice that of the Earth. What is the radius of this planet in terms of Earth’s radius?
The mean diameter of Saturn is m and the acceleration due to gravity at its surface is 9.0 m/s2. Calculate its mass.
