Lesson: Moment of a Force about a Point in 2D: Scalar Mathematics

Students will be able to

• understand that the moment of force is a measure of its tendency to cause a body to rotate about a specific point,
• understand that if the line of action of a force passes through a point, the force does not give rise to a moment about that point,
• calculate the moment of a force about a point,
• calculate the moment of the sum of a system of forces about a point,
• understand that the counterclockwise direction is defined as positive for moments.
