(Trailer) Shedding Light On Motion_ Acceleration
- Introduces students to the concept that acceleration is a measure of how quickly something changes its speed. We join James Bond as he falls out of an aeroplane without a parachute, splash into the water at 50.4 km/hr with presenter Spiro Liacos, and watch on helplessly as a truck runs off an unfinished bridge and explodes in a massive fireball.

(Trailer) Shedding Light On Motion_ Graphing Free Fall
- In this program we continue looking at graphs but pay particular attention to how graphs help us to understand the motion of objects that are either falling straight down or which have been launched vertically upwards into the air.

(Trailer) Shedding Light On Motion_ Graphing Motion
- In a 100-metre sprint, when do athletes reach their highest speed? When do they accelerate at the highest rate and at what point, if any, do they stop accelerating? In this program we look at how graphs can help us better understand the motion of athletes and of cars and other things.

(Trailer) Shedding Light On Motion_ Relative Motion
- Introduces students to the concept that the movement of an object is always relative to something else. We call it “sunrise” but is it really? Can we stand still and move around from place to place at the same time? If a car is moving forwards, can it also be moving backwards at the same time? And can we throw a single ball towards the left and towards the right at the same time? The answers to all these questions will be answered and along the way we will gain a much deeper understanding of velocity and acceleration!

(Trailer) Shedding Light On Motion_ Speed
- Introduces students to the concept that speed is a measure of how far something travels in a given amount of time, looks at how speed varies in a sprint, explains the concept of velocity, and demonstrates a number of ways of measuring an object’s speed.
