### Module summary

Classical physics is built upon Newtonian mechanics. To understand the world around us we need to learn about forces and how masses respond to them. Aristotle said "we have scientific knowledge when we know the cause". Newton's laws of motion give us a framework on which to build our scientific understanding of the Universe. In this course you will learn how to apply these laws to a wide range of systems. You will learn about linear momentum, angular momentum, torques, projectiles, rigid bodies in equilibrium, toppling, centre of mass, gravity, and conservation of mechanical energy. This will all be taught from first principles and done rigorously, assuming only a modest knowledge of A level maths. In addition, we will introduce the basic concepts of electricity and magnetism. Electromagnetic interactions are one of the four fundamental forces of nature and an essential aspect of modern technologies. You will learn about electrostatics, electric and magnetic fields, currents and resistance, capacitors, and dc circuits. You will learn to apply these concepts to a range of physical problems and see how they are important in different applications.

### Objectives

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.
- 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

Learning outcomes

 Assessment type Notes % of formal assessment In-course Assessment Regular coursework 20.00 Total percentage (Assessment Coursework) 20.00

Normally resits will be assessed by the same methodology as the first attempt, unless otherwise stated

Exams
 Exam type Exam duration % of formal assessment Standard exam (closed essays, MCQs etc) 2 hr 00 mins 80.00 Total percentage (Assessment Exams) 80.00

same as PHYS1200 and PHYS1240, Students will have to complete an in-person exam 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. Students must submit a serious attempt at all assessments, in order to pass the module overall.
