**Credit: 15****Module Organisers: ** Dr Jordi Alastruey

**Aims**

This module will provide students with a fundamental knowledge of classical mechanics, including forces, Newton’s Law, conservation of energy and momentum, single particle & rigid body dynamics, central forces and oscillations. The student will learn how to solve problems in mechanics, for example through drawing force diagrams and resolving forces, and then applying Newton’s Laws and conservation laws.

**Learning Outcomes**

On completion of the course, the students should be able to:

- To demonstrate an understanding of the theoretical basis underlying the classical laws of Newtonian mechanics, such as Newton’s Laws and the conservation laws.
- To identify the most appropriate laws to apply to complex problems in mechanics, aided by the use of annotated diagrams.
- To apply the relevant laws and equations to solve complex problems in mechanics.
- To demonstrate a physical understanding and interpretation of the resulting solutions to such problems.
