Overview

  • Air Resistance Revision of the basic ideas of Newtonian mechanics and application to particles moving under gravity.

  • The effect of air resistance and the idea of terminal velocity.

  • Oscillations The theory of oscillations of one-dimensional systems. Hooke's law for springs. Free vibrations, damped vibrations and forced vibrations. The concept of resonance.

  • Momentum and Angular Momentum Definitions and basic concepts. Rate of change of angular momentum equals moment.

  • Conservation laws. Motion under a central force. Newton's law of gravity.

  • Energy and Potentials Force fields. Gradient of a scalar function. Consevative force fields and potentials.

  • Consevation of energy.

  • Applications.

  • Inertial frames The basic ideas of inertial frames and a brief discussion of Galilean transformations.

  • Systems of Particles Centre of mass, the motion of the centre of mass. Total angular momentum of a system
    of particles. Closed systems.

  • Two body problem.

  • Collisions Elementary theory. Conservation of momentum. Elastic collisions and conservation of energy.

  • Simple applications.

Structure

5 one-hour lectures per fortnight and 1 one-hour tutorial per week.

Assessment

1st Attempt: 1 two-hour written examination (80%); in-course assessment (20%).

Resit: 1 two-hour examination (maximum of 100% resit and 80% resit with 20% in-course assessment).
Only marks gained on first sitting can be used for Honours classification.

Formative Assessment

Informal assessment of weekly homework through discussions in tutorials.

Feedback

In-course assignments will normally be marked within one week and feedback provided to students in tutorials.

Students will be invited to contact Course Coordinators for feedback on the final examination.
