Module 3: Work and energyWords like energy, power and work have very precise interpretation in physics. In this module the important link between work and energy is explored. The important principle of conservation of energy is applied to a range of situations including a rollercoaster. All around us we have building structures under tension or compression. Such forces alter the shape and dimensions of objects. If the force per unit area for a particular material exceeds a certain value, then there is a danger of the material breaking apart and this is the last thing an engineer would want. Using the appropriate materials in construction is important. In this module we explore the properties of materials.

Work and conservation of energyWork done and energy are closely related.
|
Kinetic and potential energiesThere are only really two forms of energy. The energy that a body possesses by virtue of its position (PE) and the ability to do work because it is moving (KE).
|
PowerPower is the rate of energy transfer and this part of the course looks at efficiency and how this can be calculated and shown with a sankey diagram.

Behaviour of springs and materialsThis topic will be taught through a series of tasks that allow you to investigate the material properties of metals and polymers.
