1 Dimensional Arrays>>> A standard list array - one index is needed to search for something in an array. 2 Dimensional Arrays>>> An array with 2 indexes needed to search - for example a table could be this. Interception of PseudoCode>>> The ability to pick out and explain parts of code. Big O'>>> A measure of complexity within a piece of code. Recursion>>> The process of looping, calling itself in looping. Functions>>> A decompose...

Hooke's Law>>> ∆F = k∆x where k is the stiffness of the object Stress>>> σ=F/A where F is force and A is cross sectional area Strain>>> ε=∆x/x where x is the original length of the material and ∆x is the extension Young Modulus>>> Stress/Strain Tensile stress/strain>>> Causes the length of the material to increase, the forces act away from the center Compressive stress/strain>>> Causes the length of the material to decre...

Speed>>> =distance / time Velocity>>> Is a vector and therefore has both direction and magnitude. =displacement / time Accelaration>>> =(v-u)/t Where v is initial velocity and u is final velocity Displacement time graph>>> upward slope - constant positive velocity flat line - stationary downward slope - negative constant velocity It can often be easier to just draw a distance-time graph. velocity-time graph>>> Acceleration-time graph>&gt...
