1. Chapter 7 : The technological world
Force and motion

2. Force
The capacity to do work ( movement) or cause physical change (deformation)

3. Types of Forces
The most common types of forces that cause deformation :
Tension (Traction)
Compression
Bending
Torsion
Shearing

4. Type of arrow for Forces
Big arrow

5. Tension(or Traction)

6. Compression

7. Bending

8. Torsion

9. Shearing

10. Motion Movement of an object or body caused by a force
3 types of motion
Translational
Rotational
Helical

11. Type of arrow for Motion
Small arrow

12. Translational Motion Straight line One direction : Unidirectional
Both directions : Bidirectional

13. Rotational Motion Rotate around an axis One direction : Unidirectional
Both directions : Bidirectional

14. Helical Motion Straight line + Rotation around an axis
One direction : Unidirectional
Both directions : Bidirectional

15. Exercices to do
Force : P
Motion : P
