# Module MA1242: Mechanics II

**Credit weighting (ECTS)**- 5 credits
**Semester/term taught**- Hilary term 2012-13
**Contact Hours**- 11 weeks, 3 lectures including tutorials per week
**Lecturer**- Dr. Stefano Kovacs
**Learning Outcomes****Module Content**-
- More on Momentum and Energy
(flow of mass: dynamics of systems with varying mass,
elastic and inelastic collisions, centre of mass frame);
- Some mathematical aspects
(gradient, Stokes' theorem);
- More on angular momentum
(fixed axis of rotation, motion combining translation and rotation);
- Rigid body motion
(angular velocity and angular momentum as vectors, the gyroscope,
precession);
- Gravity
(historical background: from Brahe and Kepler to Newton and from
Newton to Einstein,
Newton's law of gravitation,
inertial and gravitational mass,
experimental tests, limits of validity,
applications: elementary systems, astronomical and astrophysical
systems);
- Central forces
(two-body problem, reduced mass,
general properties of central force motion);
- Non-inertial frames and fictitious forces
(accelerating non-rotating frames,
rotating coordinate systems,
centrifugal and Coriolis forces,
tidal forces, rotating bucket and Mach's principle,
the equivalence principle and origins of General Relativity,
Galilean transformations, principle of Relativity);
- Elements of fluid dynamics.
