# Lesson Plan: Moment of a Force about a Point in 3D Mathematics

This lesson plan includes the objectives and prerequisites of the lesson teaching students how to find the moment of vector forces acting on a body about a point in 3D.

#### Objectives

Students will be able to

• express the moment of a force as a vector,
• find the moment of a force (or system of forces) in 3D when given the magnitude and direction of the forces acting on the system and the 3D coordinates of the relevant points,
• find the moment of a force (or system of forces) in 3D when given the forces acting on the system, expressed on a diagram.

#### Prerequisites

Students should already be familiar with

• finding the length of the perpendicular between the line of action of the force and a point,
• vectors,
• the vector (cross) product,
• finding the determinant of a matrix,
• moments in 2D.
