The centre of gravity of plane figure can be inside and outside of the geometrical plane figure, which affects its calculation.
Motivation phase
Short video
As you learned in the learning path named ''Centre of gravity in general'', the centre of gravity is the point where all the weight of the body is concentrated. In the next video, there is a short explanation of the previous learning path. Link to the short video: https://biteable.com/watch/3915731/041c504f42c5e4a88bb31e62abc72387

Information phase
Presentation
In this presentation, you will learn how to calculate the centre of gravity of a geometrical plane figure.
Consolidation phase
Calculate by yourself
Write the initial letter of your first name or last name in the form of geometric shapes in your notebook, dimension it as desired, and graphically and analytically determine its centre of gravity. Solve the task in the same way as second example was solved in the previous presentation. Have fun and good luck.
