Equivalently, a force is conservative if the net work it does on a particle moving between two points does not depend on the path taken by the particle. . IB Topic 4: Bonding. Carbon allotropes. pure carbon is covalently bonded in three of different forms (allotropes). graphite. diamond. fullerenes. To buy lots of super duper expensive carbon allotropes, .

Mr. Ruddle. Construction Technology. Lesson Overview. In this lesson, you will analyze the four forces that can potentially act upon structural objects: tension, compression, shear and torsion. The lesson will prepare you to be able to select appropriate materials and designs for different situations based on the types of forces that need to be accounted for.. . . Example:. What is a force? . a) Strong . nuclear . force. b) Electromagnetic force. c) Weak force. d) Gravity.. EXAMPLE? an atom . #2) There are four forces that hold all matter together. 3) Gravitational forces . The most important chapter of physics EVAR. What is a Force?. A force is a push or a pull.
