#### Chapter 2 - Kinematics

In the GCE A Levels, we need to be able to differentiate between the physical quantities distance, and displacement. This video will discuss this.

In the GCE A Levels, we need to be able to differentiate between and define the physical quantities speed, and velocity. This video will discuss this.

This video will discuss the concept of relative velocity. For the GCE A Levels, we need to be able to calculate the relative velocity of one moving object to another, and we will explore the mathematical way to calculate this.

In the GCE A Levels, we need to be able to define the physical quantity acceleration. This video will discuss all the qualitative aspects of acceleration, and we aim to have a strong understanding of this quantity.
Graphs play a big part in the GCE A Level syllabus. This video gives a brief introduction to the various tools used to analyse graphs, including reading the gradient of tangents, and computing the area under a graph.
The three quantities, displacement, velocity and acceleration have mathematical relationships that can be translated to graphs. This video will discuss the graphical relations that we need to know about these quantities for the GCE A Levels.
This video will discuss the subtle difference between instantaneous and average values of a physical quantity, and also how this can be interpreted graphically. There are several quantities in the GCE A Levels where this idea may be applied.
One of types of motion we must be able to study in the GCE A Levels is rectilinear motion. This video will explain what rectilinear motion is and describe the key quantities that characterise it.
There is a total of four equations that describe rectilinear motion in the GCE A Levels. This video will introduce these equations and describe how they are unique.
Free-fall is one of the simplest examples of rectilinear motion, yet it is one of the most commonly tested in the GCE A Levels. This video discusses very briefly how we use the equations of rectilinear motion to study an object in free fall.
In the GCE A Levels, we need to study projectile motion. This video will introduce the idea of projectile motion, the conditions required to achieve it, and some key features of an object executing projectile motion.
The GCE A Levels requires us to quantitatively analyse projectile motion. This video will equip us with the tools and knowledge to break down a projectile motion into two separate motions, and make use of simple kinematics equations to evaluate several quantities.
Drag force opposes motion, and can have significant effects on the motion of objects. In the GCE A Levels, we are required to qualitatively understand drag, and how it impacts the way objects move. This video will briefly discuss how drag affects free-fall and projectile motion.
