Description
In this episode, we introduce 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 present Spiro Liacos, and watch on helplessly as a truck runs off an unfinished bridge and explodes in a massive fireball.

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 Graphing Motion, we look at how graphs can help us better understand the motion of athletes, cars, and other things.

In Newton's First Law, presenter Spiro Liacos is 'thrown forward' in a head-on collision, 'thrown backwards' when his tram takes off, and 'thrown to the side' when his car suddely turns a corner. But in fact none of these things actually happen! Using brilliant visuals, this episode looks at the fact that an object will remain stationary or move with a constant velocity unless a force acts on it. It also describes a number of different forces that...

In Newton's Second Law, we answer the most important question that has ever been asked: how does a magician pull a table cloth out from under a dinner set? No, seriously, we look at the simple yet powerful equation 'F=ma'. Newton's Second Law tells us how to calculate the amount of force required to accelerat somthing by a given amount.

In Newton's Third Law, we look at that most poetic of all Laws: For every action there is an equal and opposite reaction. How does a rocket engine work? Why do guns recoil when fired? How do our muscles work? What propels us when we're swimming? And how exactly is gravity a two-way interaction? All these questions, and many more, will be answered in this excellent video.

In this episode, we introduce students to the concept that the movement of an object is alwayys relative to something else. We call it ' sunrise' but does the sun really rise? Can we stand still AND move around from place to place at the same time? If a care 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? All these questions will be answered...

In this episode, presenter Spiro Liacos 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.
