Key Features

gPhysics is a learning and revision software designed to help you build a good foundation in secondary level physics and develop your knowledge of the fundamental concepts. Each section presents clear outlines of important points with animations and simulations, followed by fully worked examples and a set of questions with step-by-step solutions. Built-in calculation features enable you to practise a particular style of question with values automatically suggested by the software or typed into the question text.

The gPhysics learning style encourages you to review the topics to further your understanding of the theory, before proceeding to practical activities that enhance your physics problem-solving skills. For exam preparation and good practice, it is recommended to try each question on paper and compare your answer with the solution provided by the software.

Variable-Input Questions

Each topic contains one or more variable-input questions that change each time they are displayed, which means you can repeat the same style of question with a different calculation each time. Specific values can also be typed into the changing parts of the question and gPhysics will calculate a new step-by-step solution based on the input, complete with graphs and diagrams.

By varying the parameters of a question, you can analyse the problem in more detail and see the effects on the result.

Miscellaneous Questions

A special miscellaneous questions topic helps with revision by automatically presenting questions at random from all of the different topics in gPhysics.

Simulations

gPhysics includes simulations that accept the parameters of various physical models and animate the results. These help you visualise and experiment with each theory.

For example, in the simulation of Hooke's Law, you enter the spring constant, the length of the spring, and the mass of the load. gPhysics then animates the resulting motion.

The following are the simulations included in gPhysics:

• Newton's Second Law
• Gravitation
• Energy
• Hooke's Law
• Refraction
• Diffraction
• Charge
