Lesson Plan: Center of Gravity of Laminas Mathematics • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the position of the center of gravity of a lamina composed of standard shapes in 2D.
Objectives
Students will be able to
- find the center of gravity of laminas that are rectangles, triangles, or other standard 2D shapes including semicircles,
- find the center of gravity of laminas composed of standard 2D shapes,
- find the center of gravity of a lamina with additional masses added,
- solve applied problems related to center of gravity, for example, finding unknown angle measures given that the system is suspended from a vertex.
Prerequisites
Students should already be familiar with
- moments and related calculations,
- center of gravity of particles,
- center of gravity of rods.
Exclusions
Students will not cover
- center of gravity of solids.
