### Learning Outcomes

On successful completion of this module students should be able to:

1. Understand the basic principles of gravitational and electrostatic fields and apply these to numerical examples of simple systems.

2. Describe the basic properties of dielectric, magnetic, and electrically conducting materials.

3. Calculate the force on a charged particle in electric and magnetic fields and describe the motion of a charged particle in a uniform electric field.

4. Calculate the potential of a system of charged particles.

5. Describe the structure and function of resistors, and capacitors.

6. Use phasor diagrams, vector methods and complex numbers to analyse AC circuits.

7. Describe basic principles underlying atomic, nuclear and particle physics and apply these to examples of simple systems.

### Brief description

The module discusses the forces arising from gravitational and electrostatic fields and describes these in terms of the inverse square law with illustrative examples. Associated fields and potentials are also described. Electric charge and current, magnetic fields and electromagnetic induction are used to describe the operation of electric circuits and the properties of dielectric and magnetic materials. The module also gives an introduction to basic physics underpinning atomic, nuclear and particles physics.

### Aims

The module considers the principles underlying gravitational and electrostatic fields and introduces magnetism, electricity and electric circuits. It also introduces basic concepts in atomic, nuclear and particle physics. Emphasis is placed on the solution of problems, and examples sheets include numerical exercises. This module prepares students for more advanced modules in Part 2.
