Mechanics is the branch of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. In Grade 11, the following topics will be covered under this Mechanics Module
- Vectors in two dimensions
- Resultant of perpendicular vectors,
- Resolution of a vector into its parallel and perpendicular components
- Newton’s Laws and Application of Newton’s Laws
- Newton’s first, second and third laws and Newton’s law of universal gravitation,
- Different kinds of forces: weight, normal force, frictional force, applied (push, pull), tension (strings or cables),
- Force diagrams, free body diagrams and
- Application of Newton’s laws(equilibrium and nonequilibrium)
