Mechanics 1 

This course is an introduction to the area of physics relating to forces and the motion of particles. We start from basic assumptions to see how complex problems can be reduced to solvable ones.

Chapter 1 - Mathematical Models in Mechanics

In this first chapter we look at some of the basic assumptions we will be making throughout this course. We then look the SI base and derived units, and how to convert units, before an overview of force diagrams is given.

Chapter 2 - Constant Acceleration

By first considering various graphs of motion, we derive the so-called ‘SUVAT’ formulae of particles undergoing constant acceleration. We then introduce gravity, and look at problem solving for particles moving freely under gravity.

Chapter 3 - Vectors in Mechanics

We look at vectors in 2 dimensions and how they can be used to represent velocities, accelerations, displacements and forces. We see the concept of a bearing, before using vector equations to solve dynamical problems.

Chapter 4 - Dynamics of a Particle Moving in a Straight Line

Here we consider Newton’s Second Law to see how forces lead to acceleration and motion. We then consider connected particles, and use Newton’s Third Law to see how they interact with each other through forces.

Chapter 5 - Forces and Friction

We now look at forces acting at an angle, and how to resolve forces in perpendicular directions. Next we look at friction, and how through the coefficient of friction we can determine the frictional force between two objects in contact with each other.

Chapter 6 - Momentum and Impulse

By considering the action of a force over time, we can look more generally at what is called the impulse of a force. This in turn leads to a discussion of Momentum, which is conserved when objects in motion collide.

Chapter 7 - Statics of a Particle

When the forces are balanced just right, [ object can be in static equilibrium i.e. not moving, not accelerating. Knowing that objects are in equilibrium allows us to apply some unique problem solving techniques to a new set of situations.

Chapter 8 - Moments

The rotational effect of a force about some pivot point is called its Moment. We introduce looking at Moments, and then go on to deal with equilibrium problems for both uniform and non-uniform rods.
