In this chapter we will learn about describing position with a reference point, distance travelled and displacement, average speed, average velocity and average acceleration, representing motion with position-time and velocity-time graphs, the kinematic equations for constant acceleration, and uniform circular motion.
Describing
We pin motion down precisely — in words, numbers, equations and graphs — instead of just "fast" or "slow".
Motion
A change of position with time, measured against a chosen reference point and direction.
Around
Everyday motion — runners, falling balls, cars, trains, merry-go-rounds — simplified to straight-line and circular models.
Us
Why it matters to people: safe braking distances, speedometers, and the physics behind real journeys.
