ENGINEERING SCIENCE N4 – COMPLETE STUDY NOTES

Module 1: Dynamics (Rectilinear & Angular Motion)

1.1 Rectilinear Motion (Straight Line)

• Newton’s Laws of Motion

  2. Step-by-Step Worked Examples

  You cannot learn dynamics by reading definitions. Your PDF must show how to solve a problem. For example:

  Formula Sheet (Summary)

  | Quantity | Formula | |----------|---------| | Force | ( F = ma ) | | Weight | ( W = mg ) | | Velocity (linear) | ( v = u + at ) | | Velocity (angular) | ( \omega = \omega_0 + \alpha t ) | | Centripetal force | ( F_c = mv^2/r ) | | Work | ( W = Fs\cos\theta ) | | Power | ( P = Fv ) | | Efficiency | ( \eta = (P_out/P_in) \times 100 ) | | Pressure (static fluid) | ( P = \rho gh ) | | Continuity | ( A_1v_1 = A_2v_2 ) | | Bernoulli | ( P + \frac12\rho v^2 + \rho gh = const ) | | Ideal gas | ( PV = mRT ) | | Stress | ( \sigma = F/A ) | | Strain | ( \varepsilon = \Delta L/L ) | | Young’s modulus | ( E = \sigma/\varepsilon ) | engineering science n4 pdf notes
