### Objectives

At the end of this module you should be able to:
- describe the motion of particles in terms of their position, velocity and acceleration;
- discuss Newton's laws in the context of cause and effect;
- derive the work-energy theorem and define potential energy from a conservative force;
- discuss and utilise the conservation of momentum for a system of particles;
- discuss and utilise the conservation of angular momentum for rigid body rotation;
- describe and utilise Newton's theory of gravity;
- describe the basic mechanical properties of solids and fluids.
- derive and use the transformation equations of special relativity;
- compute the energy and momentum of relativistic particles;
- summarise relativistic systems on a Minkowski spacetime diagram;
- understand the core difference between quantum and classical physics;
- represent quantum systems with two classical states;
- compute measurement probabilities and quantum evolutions;
- apply the Heisenberg uncertainty relation and de Broglie wavelength to concrete physical systems;
- derive the Bohr model and use it to estimate energies of atoms and molecules;
- perform elementary computations relating to photons and radiation;
- understand the uses and philosophical implications of quantum entanglement;
- understand and solve problems involving the Coulomb force;
- perform calculations on DC circuits (including capacitors, resistors and inductors) using Ohmâ€™s and Kirchhoff's Laws);
- calculate the force on a charge moving in a magnetic field
