Learning Outcomes
On completion of this module, students should be able to:
1. Describe the basic principles of dynamics.
2. Solve numerical problems in translational motion, rotational motion and oscillations, and interpret the results in the physical context.
3. Model problems in dynamics using mathematical equations.
Brief description
The module provides an introduction to the classical theory of dynamics. It comprises three main parts, following a brief recap of vector manipulation. The first part covers classical kinematics, Newton's Laws of Motion, momentum, forces, work and mechanical energy. The second part introduces rotational motion and illustrates the parallels with translational motion. The theory of oscillations is introduced in the third part, covering the classical harmonic oscillator, resonance, and coupled oscillators.
Aims
The module develops the student's understanding of the principles and techniques of dynamics. Emphasis is placed on solving problems, and numerical examples are provided for the student to practice. The module is appropriate as a first-year core module in Physics and Mathematics honours degree schemes, and it prepares the student to use the topics in more advanced Part 2 modules.
Content
Vector and scalar quantities. Position vector. Orthogonal unit vectors.
Manipulation of vectors: addition, resolving, scalar and vector products.
TRANSLATIONAL MOTION
1. Kinematics of a particle: constant acceleration, projectile motion.
2. Newton's Laws of Motion: momentum, weight, contact forces on solids, friction, circular motion and centripetal force, drag force.
3. Work and Energy: work done by force, kinetic energy, power, conservative force, potential energy (gravitational and spring), conservation of mechanical energy.
4. Conservation of momentum: centre-of-mass, collisions, coefficient of restitution.
ROTATIONAL MOTION
1. Rotation of solid bodies: moment of inertia, angular momentum, torque, angular acceleration.
2. Parallels between translational and rotational motion.
OSCILLATIONS
1. Simple Harmonic Motion: period, amplitude, velocity, acceleration, energy.
2. Simple Harmonic Motion in mechanical systems.
3. Damped and forced oscillations, resonance.
4. Coupled oscillations: normal modes.
