# PHS1722 - Physical science

## 6 points, SCA Band 2, 0.125 EFTSL

#### Offered

Gippsland Second semester 2007 (Day)

Gippsland Second semester 2007 (Off-campus)

#### Synopsis

This unit provides the student with a basic knowledge of a range of physical science topics and skills that are important for students proceeding toward a science degree. Topics covered include: force, work and energy; circular motion; heat transfer and thermal properties; the laws of thermodynamics; electrical charges and their properties; analysis of simple electrical circuits; magnetism and its applications; an introduction to quantum theory; radioactive decay, radiation measurement and safety. The emphasis in approach is on the application of physical principles. Some mathematical problem solving is included, but a knowledge of calculus is not assumed.

#### Objectives

On completion of this unit, students will be able to apply Newton's laws, the work-energy principle and conservation of energy to analyse simple dynamics problems; apply kinetic theory and the gas laws to explain heat transfer, temperature and thermal properties of materials; apply the laws of thermodynamics and the concept of entropy to describe thermal processes; apply Coulomb's law to simple charge distributions to determine forces, electric field strengths and potentials; analyse simple DC circuits involving series and parallel resistors; determine the force on moving charges in magnetic fields; describe the concept of magnetism, its production and use in electromagnetic devices and instruments; understand the quantum nature of radiation and explain its role in the photoelectric effect; describe different types of radioactive decay, the fundamental emissions associated with these and solve problems using decay rates or half-lives; understand the concept of binding energy and its role in nuclear stability; describe the passage of radiation through matter and the basic principles of dosimetry.
