Centre of gravity
| Language: | English |
|---|---|
| Description: | The centre of gravity of a body is the point in which the mass of the body can be concentrated. Gravity acts as if all the mass of the body is concentrated in that point. This lesson allows the student to explore the concept of gravity and to find the centre of gravity of an irregular body. |
| Target: | Key Stage 3 |
| Category: | Exercise |
| Discipline: | Static forces, Gravity |
| Learning objectives: |
Understand and explain the concept of centre of gravity. Discuss methods of finding centre of gravity of an irregular body. Model a situation for centre of gravity and create an interactive simulation. |
| In class: | Discuss the centre of gravity.
What does it mean and what effect does this phenomenon have in real life? How can the centre of gravity of a body be found? Discuss possible ways of doing this with the class and put up suggestions on the board. Discuss how this can be visualized and explored in Algodoo. Let the students create scenes in Algodoo using the suggestions you came up with together or let them use their own ideas. Help the students make decisions and ask guiding questions. Encourage the students to follow the procedure Create – Predict – Interact – Evaluate. Allow the students to follow-up and share their experiences in class after the simulation. |
