STEP 3 Mechanics
This module contains Mechanics questions based on the STEP 3 specification. Each STEP 3 module consists of STEP questions, some topic notes and useful formulae, a "hints" sheet and a "solutions" booklet. STEP questions are challenging, so don't worry if you get stuck. These STEP 3 modules assume that you have already begun to develop your problem-solving skills and approach to STEP questions by working on the Foundation modules and the STEP 2 modules.
About this assignment
The first steps in tackling a Mechanics question are to draw a large, clear diagram and to have a think about what is happening physically. There are several extra topics in the STEP 3 specification, including motion in a circle, oblique collisions and simple harmonic motion. A lot of the questions require you to set up several equations and then do some algebraic manipulation to show a given result.

Hints, support and self evaluation
The “Hints" file gives suggestions and some starting points on how you can tackle the questions. The "Solutions" file leads you through one possible solution, but some steps will be missing and you will still need to work through the question yourself.
