Practise and test
By the end you can
Use W = mg and tell mass from weight Find resultant forces, draw free body diagrams and resolve a force (Higher) Calculate work done with W = Fs Use F = ke and ½ke², and carry out the spring required practical Use the principle of moments for levers and gears (Physics only) Calculate pressure with p = F/A and p = hρg, and explain upthrust (Physics only) Revision notes
