  1. Physics 12 Forces and Equilibrium Concept Map S. Coghlan

  2. This concept map is designed to help you; Understand how the various different parts of forces and equilibrium link together. Study the whole section of work. Main Concepts Printer friendly version available from my web site Linking words S. Coghlan

  3. Principal of moments CM = ACM Torque F x d Centre of mass Centre of gravity Equilibrium may produce have involves show Forces and Equilibrium

  4. Centre of mass Centre of gravity Torque F x d Principal of moments have may produce involves show Equilibrium Forces and Equilibrium

  5. CM = ACM • FV = 0  FH = 0 • M = 0 Stable Neutral Unstable rotational equilibrium types conditions Centre of gravity Torque F x d Centre of mass Principal of moments have may produce involves show Equilibrium Forces and Equilibrium

  6. CM = ACM Centre of gravity rotational equilibrium Torque F x d Centre of mass Principal of moments Stable have may produce involves types Forces and Equilibrium show Equilibrium Neutral conditions Unstable  FH = 0  FV = 0  M = 0

  7. Your own concept map Single page concept map The End Forces and Equilibrium Concept Map S. Coghlan

  8. Main Concepts You can use these Main Concepts and Linking Words to complete your own concept map. You can print out the next page and use it as a framework. • Principal of moments • CM = ACM Torque F x d • Centre of mass Centre of gravity • Equilibrium • CM = ACM • FV = 0  FH = 0 • M = 0 Stable Neutral Unstable Linking Words may produce involves have show rotational equilibrium types conditions strain Printer friendly version available from my web site

  9. Printer friendly version available from my web site Equilibrium

  10. CM = ACM Centre of gravity rotational equilibrium Torque F x d Centre of mass Principal of moments Stable have may produce Neutral involves types Structures & Materials show Equilibrium conditions Unstable  FH = 0  FV = 0  M = 0

  11. Centre of Mass = Centre of gravity Centre of Mass  Centre of gravity 1 m Uniform object - geometrical centre. Gravitational field strength, g, is the same everywhere for the body. Object is so large that the gravitational field strength may not be the same everywhere over the body.

  12. Torque Force Force Torque = F x d Lever d Lever d Pivot Point Pivot Point d is always at right angles to the line of action of the force

  13. If slightly pushed, and released; returns to its original position remains displaced continues to move and c of m lowers Neutral equilibrium Unstable equilibrium Stable equilibrium
