[French] Physics: Global plan for solving exercises

The teacher explains the main steps involved in solving a physics exercise. First of all, you have to read the question carefully, crossing out the irrelevant points and highlighting the essential ones. To illustrate the situation, you need to draw a simple but precise schematic diagram. All the data in the question are listed with the appropriate symbol and the corresponding unit. The unknown is marked with a question mark. The formulae are established and noted. To find the solution, the symbols in the formulae are replaced by the corresponding values and a mathematical calculation is performed. First of all, we ask ourselves whether the final answer makes sense. If it does, it can be highlighted with a marker.
