PHY 213: Classical Physics I



Learning Outcomes
On Completion, the students should be able to;
1. relate the concepts of space coordinates, time and linear motion;
2. describe particle dynamics, equilibrium and conservative forces;
3. solve problems on central forces, energy and angular momentum,
4. explain the dynamics of rotational motion;
5. discuss and apply the potential theory;
6. explain the dynamics of rigid bodies;
7. apply Newton’s theory of gravitation to problems of planetary motion and space travel;
8. use inertial forces to explain motion from the viewpoint of rotating frames of reference; and
9. derive the general relation between the angular velocity and angular momentum of a rigid
body, and use this to solve problems in rotational dynamics.
