Brief description
This module explores the success of Newtonian physics in explaining the world around us - from the behaviour of gases to the orbit of planets. Starting from the cornerstone of Newton's three laws, the module progresses to examine the interaction of forces and material objects and introduces the concept of a central force field. Topics covered include: conservation laws, rotational motion, gravitational fields and potential, projectiles and intermolecular forces.

Learning outcomes
After taking this module students should be able to:

• Understand how Newtonian mechanics can be used to describe the behaviour of simple mechanical systems, and be able to apply that understanding to solve simple problems in this area.

Additional learning activities
Four workshops are to take place at appropriate intervals throughout the course to develop problem solving skills in this subject.
