Combining some fundamental physics with trigonometry and computer programming, this guide helps students to create a simulation of the projectile motion of a cannon ball. The concepts are all briefly explained, and the program introduces some clever mathematics as well as game elements, such as collision detection...

This issue of the magazine, presenting the fun side of computer science, includes articles on:

• The nature of artificial intelligence

• Computer generated images and motion capture in the movies

• The efficiency of insect brains

• JPEGs and the psychology of image compression

This Catalyst article uses physics to investigate the possible causes of the sinking of the Titanic. Mike Follows explains how the hull of the Titanic was constructed to be watertight, however, the strength of the rivets used on the ship were inadequate.

The article shows how the alignment of the sun, Earth...

Published by the Nuffield Foundation, the articles in this Revised Nuffield Advanced Physics reader are extended concepts covered in the course and examined developments in physics taking place in the 1980s.

Royal Navy Search and Rescue helicopters provide cover to large sections of the UK coastline, offering support to coastguard services 365 days a year.

These materials from Defence Dynamics encourage the use of problem solving skills and knowledge of trigonometry to directly assist the Royal Navy in a series...

This computer animation special is issue 11 of the series Computer Science for Fun. It features a range of articles covering:

• The history of computer animation

• Animation basics

• Automata – precursors to computers

• Soap bubbles and the Travelling Salesman Problem

• Motion...

A Catalyst article about road traffic accidents (RTAs). After the accident police and other investigators try to establish what went wrong. This may be with a view to prosecuting a motorist, or simply in an effort to improve road safety. An understanding of the physics of motion plays a large part in such...

This booklet, from Science Community Representing Education (SCORE), offers a range of practical activities for use in the classroom. Most are aimed at Key Stage Three and Four and Post-16 students but a small number are provided for Key Stage Two to highlight the...

This Catalyst article investigates the ideas traffic police use about speed, acceleration and force to determine what happened during road accidents. The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 2.

Catalyst is a...

A Catalyst article about physicists working at Europe’s Large Hadron Collider who hope to have received the first results from what is probably the biggest, most expensive and most ambitious scientific experiment ever carried out. Later, they hope to solve the mystery of the fundamental forces of nature.

The...

This booklet, from Science Community Representing Education (SCORE), offers a range of practical activities and experiments for use in the classroom. Most are aimed at Key Stages One and Two students but a small number are provided for Key Stage Three to highlight the...

This Catalyst article explores how cyclists can use physics to explain certain limitations to their performance. Variables which may affect a cyclist's speed such as force, energy and power are considered along with formulas for calculating the correct amount of each in order to optimise performance.

The...

This Catalyst article looks at how computer games make increasingly sophisticated use of the laws of physics to produce convincing on-screen effects. From calculating the angle that a ball bounces off a wall to modelling the frictional forces on a rally car, physics has always played a part in the development of...
