Lesson: Surface Gravity Physics • First Year of Secondary School

In this lesson, we will learn how to calculate the surface gravity of a planet or moon given its mass and its radius.

Lesson Plan

Students will be able to

understand that the acceleration due to gravity, , experienced by an object in the vicinity of a large object with mass is dependent on and the radial distance between the centers of mass of the two objects, ; so, ,
use to calculate the acceleration due to gravity on the surface of a large body,
understand that the acceleration due to gravity experienced by object in the vicinity of a large object is the same whatever the mass of .
