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

Students will have to complete an online assessment at the end of the module. This will take place during the examinations period at the end of the semester and will be time bound. The assessment will not take 48 hours to complete, but students will have a 48 hour time period in which to complete it. Students are required to pass all assessments for this module in order to pass the module overall.
