Aims and Objectives

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • Newton's laws of motion and their application to systems in equilibrium, and to rigid bodies moving under the action of simple systems of forces.
