Lectures, laboratories, demonstrations, research, project work and some study will be used to ensure the student has a wide range of experiences.

Module Aim:

The aim of this module is to provide the learner with an introduction to the principles of physics and their importance and relevance to sustainable agricultural science and engineering. The module will develop practical laboratory skills.

Learning Outcomes

On successful completion of this module the learner should be able to:

LO1

Interpret written descriptions of practical static and dynamic problems relating to agricultural engineering applications.

LO2

Translate written descriptions of practical static and dynamic engineering problems into mathematical form.

LO3

Apply and solve formulae involving the interaction of the motion of an object and the forces and torques to which it is subjected with particular emphasis on agricultural applications.

LO4

Analyse mathematically the relationship between the motion of a particle/rigid body and the forces to which it is subjected by the appropriate methods - Force-Mass-Acceleration/Energy/Impulse/Momentum - as applied to agricultural engineering applications.

LO5

Contribute effectively, as an individual and as part of a group, to the planning and realization of investigations in a laboratory environment into the effects of applied forces on components. Report on the findings
