UCL Mechanical Engineering
Faculty of Engineering Sciences


MECH104P Engineering Dynamics

The aims of the course are two-fold. First, it aims to teach the basic analytical methods, that is, the fundamental concepts and techniques of engineering dynamics. Second, it aims to show the implementation of these methods in the design and analysis of simple basic mechanisms.

Code: MECH104P
Alt Codes: None
Title: Engineering Dynamics
Level: 1
UCL Credits/ECTS: 0.5/7.5
Start: January
End: April
Taught by: Dr. PJ Tan (module coordinator)


  • ENGS103P Mathematical Modelling and Analysis and MECH101P Introduction to Mechanical Engineering. A-level physics and Maths will not be a substitute.

Method of Instruction

Lectures and tutorials. Tutorial sheets and other exercises will be used to provide formative assessment. Practical classes related to the reinforcement of conceptual ideas taught in this subject will be conducted and assessed in MECH102P Mechanical Engineering Practical Skills I.

MECH104P Engineering Dynamics


  • Examination (100%)

To pass this course, students must:

Obtain an overall pass mark of 40% for all sections combined


The course concentrates on dynamics where the concepts of Newton’s Law of motion, forces, work, energy, momentum and impulse will be covered and explained in depth using examples from everyday phenomenon such as ‘Why do hurricane in the northern hemisphere rotate counter-clockwise?’, ‘What is the energy loss from two colliding snooker balls?”, “Where should a door-stopper be placed to prevent the door hinges from coming loose?”.

The course will cover the following:

1 . Kinematics of Particles

  • Rectilinear motion
  • Curvilinear motion
  • Relative motion

2 . Kinetics of Particles- Newton’s 2nd Law

  • Force, mass and acceleration
  • Inertial reference frame

3 . Kinetics of Particles- Energy and Momentum Principles

  • Work and kinetic energy
  • Potential energy
  • Impulse and momentum
  • Linear and angular momentum

4 . Systems of Particles

  • Application of 2 & 3 to systems of particles

5 . Kinematics of Rigid Bodies

  • Pure rotation
  • Relative velocity and acceleration
  • Sliding contact
  • Moving reference frames


6 . Plane Motion of Rigid Bodies- Forces and Accelerations

  • Force – linear momentum principle
  • Moment – angular momentum principle
  • D’Alembert’s principle
  • Fixed axis rotation
  • General planar motion

7 . Plane Motion of Rigid Bodies- Energy and Momentum Methods

  • Work and kinetic energy
  • Impulse and Momentum principle for rigid body
  • Conservation of angular momentum
  • Impulsive motion
