# Background Knowledge

This article is a topic within the subject Higher Physics 1A.

## Contents |

## Introduction

For (Higher) Physics 1A you will need a working knowledge of several concepts from the HSC maths and physics courses. This page lists these concepts briefly, but should not be considered a comprehensive guide to any HSC course.

## Physics

(Higher) Physics 1A does not assume any prior physics knowledge, but will move quickly through some concepts that were covered in high school^{[1]}. Some useful revision can be found on the HSC Online Physics site provided by Charles Sturt University. The HSC topics relevant to this course are listed below, with the key concepts sub-listed.

- The Earth's Gravitational Field
- Gravitational fields
- Work and gravitational potential energy
- Weight and acceleration due to gravity (F=mg)

- A successful rocket launch
- Projectile motion
- Escape velocity
- Variations in Earth's gravity
- Momentum and Impact
- Orbits and circular motion
- Kepler's laws

- The Solar System is held together by gravity
- Newton's Law of Universal Gravitation
- Orbits and centripetal force
- The slingshot effect

- The Earth's Gravitational Field

The following concepts from Year 11 Physics will also provide helpful background knowledge for (Higher) Physics 1A:

- Vectors
- Waves and superpositioning
- Distance-time graphs and velocity-time graphs

## Maths

(Higher) Physics 1A assumes knowledge of various High School Mathematics concepts^{[2]} (from earlier years as well as the HSC syllabus):

- Plotting and reading graphs
- Appropriate use of significant figures
- Solving quadratic equations
- Exponential and log
- Solving simultaneous equations
- Trigonometric functions and some identities
- Differentiation and integration
- Solving simple differential equations

The following HSC Mathematics topics are not assumed knowledge, but provide a helpful background to the topics covered in (Higher) Physics 1A:

- Simple harmonic motion (Mathematics Extension 1)
